Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 PM PDT Thu Sep 19 2019

For the eastern North Pacific...east of 140 degrees west longitude:

The National Hurricane Center is issuing advisories on Tropical
Storm Kiko, located over the far southwestern part of the basin, on
Tropical Storm Mario, located several hundred miles south of the
southern tip of the Baja California peninsula, and on Tropical Storm
Lorena, located near the Islas Marias Islands.

Thunderstorm activity associated with an elongated area of low
pressure located over the far southwestern portion of the eastern
North Pacific remains disorganized. Some slow development of this
system is possible during the next day or two while it remains
nearly stationary. Further development is unlikely after that time
as the system interacts with and is possibly absorbed by Kiko.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.

An area of low pressure could form south of the southern coast of
Mexico in a day or two. However, development into a tropical
cyclone during the next five days appears unlikely.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...near 0 percent.

Issued at 600 PM MDT Thu Sep 19 2019 000 WTPZ35 KNHC 192331 TCPEP5 BULLETIN Tropical Storm Lorena Intermediate Advisory Number 10A NWS National Hurricane Center Miami FL EP152019 600 PM MDT Thu Sep 19 2019 ...CENTER OF LORENA NOW MOVING AWAY FROM THE ISLAS MARIAS... SUMMARY OF 600 PM MDT...0000 UTC...INFORMATION ---------------------------------------------- LOCATION...21.9N 107.3W ABOUT 185 MI...300 KM ESE OF CABO SAN LUCAS MEXICO MAXIMUM SUSTAINED WINDS...70 MPH...110 KM/H PRESENT MOVEMENT...NW OR 315 DEGREES AT 12 MPH...19 KM/H MINIMUM CENTRAL PRESSURE...994 MB...29.36 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Hurricane Warning is in effect for... * Baja California peninsula from La Paz to Santa Fe A Hurricane Watch is in effect for... * East coast of the Baja California peninsula north of La Paz to San Evaristo * West coast of the Baja California peninsula north of Santa Fe to Puerto Cortes A Tropical Storm Warning is in effect for... * Manzanillo to Punta Mita A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area, in this case within the next 24 hours. Preparations to protect life and property should be rushed to completion. A Tropical Storm Warning means that tropical storm conditions are expected within the warning area. A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. Interests elsewhere in Baja California Sur should monitor the progress of Lorena. Additional watches or warnings may be required for portions of this area later tonight or Friday morning. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 600 PM MDT (0000 UTC), the center of Tropical Storm Lorena was located near latitude 21.9 North, longitude 107.3 West. Lorena is moving toward the northwest near 12 mph (19 km/h). A turn to the west-northwest is expected tonight, and a west-northwestward motion at a slower forward speed should continue through Saturday. On the forecast track, the center of Lorena will move over the Pacific waters to the southeast of the Baja California peninsula tonight, pass near or over the southern portion of the Baja California peninsula on Friday, and move along the west coast of the peninsula Friday night and Saturday. Maximum sustained winds are near 70 mph (110 km/h) with higher gusts. Strengthening is forecast during the next day or so, and Lorena is forecast to re-gain hurricane strength as it approaches the Baja California peninsula. Tropical-storm-force winds extend outward up to 70 miles (110 km) from the center. The estimated minimum central pressure is 994 mb (29.36 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Lorena can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP5 and WMO header WTPZ45 KNHC and on the web at www.hurricanes.gov/text/MIATCDEP5.shtml. WIND: Tropical storm conditions will continue within portions of the tropical storm warning area in southwestern Mexico for a few more hours. Hurricane conditions are expected within the hurricane warning area in the southern Baja California peninsula on Friday, with tropical storm conditions beginning late tonight. Hurricane and tropical storm conditions are possible within the hurricane watch area by Saturday. RAINFALL: Lorena is expected to produce the following rainfall amounts through the weekend: Coastal sections of the Mexican states of Michoacan, Colima and Jalisco: 5 to 10 inches with maximum amounts of 15 inches. This rainfall may produce life-threatening flash floods and mudslides. Far southern Baja California Sur: 2 to 4 inches with maximum amounts around 6 inches. SURF: Swells generated by Lorena will affect portions of the southwestern coast of Mexico and the southern Baja California peninsula during the next few days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

Issued at 300 PM MDT Thu Sep 19 2019 000 WTPZ44 KNHC 192053 TCDEP4 Tropical Storm Mario Discussion Number 10 NWS National Hurricane Center Miami FL EP142019 300 PM MDT Thu Sep 19 2019 It's become clear since the issuance of the last advisory that the low level center of Mario is displaced well east of its convection. In fact, a good portion of the center has been exposed this afternoon. The intensity has been lowered to 50 kt based on a blend of the most recent Dvorak Final-T and Current Intensity numbers from TAFB. A significant change to the track forecast was required based on the adjusted initial position of Mario, and the cyclone is now forecast to move much farther east during the next couple of days. The track models are still in extremely poor agreement on how much Mario and Lorena will interact over the next 2 days, and this is further complicated by the fact that Lorena will move over or very near the Baja California peninsula during that time. The NHC forecast still carries Mario as an independent system through 5 days, but confidence in the forecast remains low. For better or worse, the NHC forecast is close to TVCE at most of the forecast period, but is now just east of the consensus for the first 24 h, given current trends. Merger or not, shear from Lorena will likely affect Mario for the next couple of days. As long as Lorena continues to produce substantial convection, this shear should prevent Mario of significantly strengthening, though small short-term fluctuations are still possible. By the end of the forecast period, Mario is forecast to reach cooler waters and encounter dry air, and will likely become post-tropical. The new official intensity forecast is close to the intensity consensus IVCN throughout the forecast period.

Issued at 200 PM PDT Thu Sep 19 2019 000 WTPZ43 KNHC 192045 TCDEP3 Tropical Storm Kiko Discussion Number 30 NWS National Hurricane Center Miami FL EP132019 200 PM PDT Thu Sep 19 2019 In terms of organization (and latitude) Kiko appears to have hit rock bottom and may now be on its way back up (and north). After the last advisory, Kiko briefly lost all of its central deep convection and consisted of a low-level swirl of clouds. Since then, convective activity has increased substantially and now a rain band appears to be trying to wrap around the northern semicircle of the tropical storm. ASCAT data around 1800 UTC showed max winds of only 35-40 kt, but given the improvement in the structure of Kiko since that time, the initial intensity is conservatively lowered to 45 kt. Aside from small adjustments due to the lower initial intensity, little change was made to the intensity forecast. Most of the guidance calls for at least slight strengthening, and the dynamical models are still calling for Kiko to become a hurricane again. Dry air is still the primary limiting factor, and if Kiko can ever reform a well-defined inner-core, it could strengthen more quickly than forecast. By the end of the forecast period, Kiko could encounter an even drier environment and most of the guidance calls for weakening. Kiko is beginning to turn west-northwestward, and a turn toward the northwest is expected soon. The tropical storm is still forecast to move slowly westward on a wave-like path due to fluctuations in the strength of a mid-level ridge to the north. The track guidance is in particularly poor agreement on the speed Kiko will move west and by day 5 the ECMWF and GFS are 750 mi apart. Although only minor changes were made to the NHC forecast, which remains near the model consensus, confidence in the track forecast is much lower than usual.

Issued at 300 PM MDT Thu Sep 19 2019 000 WTPZ45 KNHC 192037 TCDEP5 Tropical Storm Lorena Discussion Number 10 NWS National Hurricane Center Miami FL EP152019 300 PM MDT Thu Sep 19 2019 The center and structure of Lorena was extremely difficult to determine this morning after the core of the tropical cyclone interacted with the mountainous terrain of southwestern Mexico. The aircraft that was scheduled to investigate Lorena had mechanical issues and was unable to complete its mission. Thankfully, a fortuitous GMI microwave overpass around 1800 UTC and more recent ASCAT data has provided some clarity on the location and structure of the cyclone. According to that data, the center is located just southwest of the Islas Marias, and the ASCAT revealed peak winds of 45-50 kt. Given the typical undersampling of the ASCAT for in small tropical cyclones, the initial intensity is set at 60 kt, which is between the peak scatterometer winds and the higher satellite estimates. Since the microwave data suggests that the inner core appears to be somewhat intact, some strengthening is expected while the cyclone moves over warm water and remains in a low shear environment during the next 24 hours or so. As a result, Lorena is forecast to be a hurricane when it pass near or over the southern Baja peninsula. After that time, interaction with land is likely to cause some decrease in wind speed. Lorena has been moving faster than expected, and the initial motion estimate is 315/11 kt. The cyclone should turn west-northwestward tonight as it moves between a mid-level ridge to its northeast and Tropical Storm Mario to the southwest. If Lorena remains separated from Mario (as shown by the latest ECMWF), a turn back toward the northwest is expected as the storm moves around the southwestern portion of the ridge. The new NHC track forecast lies between the HFIP corrected consensus model and the latest ECMWF. Although there is still quite a bit of uncertainty regarding the exact track and intensity of Lorena, the government of Mexico has issued a Hurricane Warning for a portion of the southern Baja California peninsula. Key Messages: 1. Heavy rainfall will continue over portions of the Mexican states of Michoacan, Colima, and Jalisco during the next day or so. This rainfall may produce life-threatening flash flooding and mudslides. 2. Tropical-storm-force winds are expected to continue along a portion of the coast of southwestern Mexico through this evening. 3. Lorena is forecast to re-strengthen into a hurricane and bring hurricane-force winds and heavy rainfall to a portion of the southern Baja California peninsula beginning on Friday. A Hurricane Warning has been issued, and preparations to protect life and property should be rushed to completion.

Preparations to protect life and property should be rushed to completion. A Tropical Storm Warning means that tropical storm conditions are expected within the warning area. A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. Interests elsewhere in Baja California Sur should monitor the progress of Lorena. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 300 PM MDT (2100 UTC), the center of Tropical Storm Lorena was located near latitude 21.6 North, longitude 107.0 West. Lorena is moving toward the northwest near 13 mph (20 km/h). A turn to the west-northwest is expected tonight, and a west-northwestward motion at a slower forward speed should continue through Saturday. On the forecast track, the center of Lorena will move over the Pacific waters to the southeast of the Baja California peninsula tonight, pass near or over the southern portion of the Baja California peninsula on Friday, and move along the west coast of the peninsula Friday night and Saturday. Maximum sustained winds are near 70 mph (110 km/h) with higher gusts. Strengthening is forecast during the next day or so, and Lorena is forecast to re-gain hurricane strength as it approaches the Baja California peninsula. Tropical-storm-force winds extend outward up to 70 miles (110 km) from the center. A Mexican navy automated station on Isla Maria Madre island recently reported sustained winds of 45 mph (73 km/h) and a wind gust of 65 mph (105 km/h). The estimated minimum central pressure is 994 mb (29.36 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Lorena can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP5 and WMO header WTPZ45 KNHC and on the web at www.hurricanes.gov/text/MIATCDEP5.shtml. WIND: Tropical storm conditions will continue within portions of the tropical storm warning area in southwestern Mexico through this evening. Hurricane conditions are expected within the hurricane warning area in the southern Baja California peninsula on Friday, with tropical storm conditions beginning late tonight. Hurricane and tropical storm conditions are possible within the hurricane watch area by Saturday. RAINFALL: Lorena is expected to produce the following rainfall amounts through the weekend: Coastal sections of the Mexican states of Michoacan, Colima and Jalisco: 5 to 10 inches with maximum amounts of 15 inches. This rainfall may produce life threatening flash floods and mudslides. Far southern Baja California Sur: 2 to 4 inches with maximum amounts around 6 inches. SURF: Swells generated by Lorena will affect portions of the southwestern coast of Mexico and the southern Baja California peninsula during the next few days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
