DISCUSSION AND OUTLOOK ---------------------- At 100 PM CDT (1800 UTC), the center of Tropical Storm Lorena was located near latitude 13.9 North, longitude 100.4 West. The tropical storm is moving toward the northwest near 15 mph (24 km/h). A northwestward motion at a slightly slower speed is expected for the next couple of days. Lorena is expected to move near the southwest coast of Mexico by Thursday. Recent satellite-derived wind data indicate that Lorena's maximum sustained winds have increased to near 45 mph (75 km/h) with higher gusts. Continued gradual strengthening is anticipated during the next couple of days as Lorena approaches the coast of Mexico. Tropical-storm-force winds extend outward up to 45 miles (75 km) from the center. The estimated minimum central pressure is 1004 mb (29.65 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are possible within the southern portion of the watch area by late Wednesday or early Thursday and could then spread northward along the coast through late Thursday. RAINFALL: Lorena is expected to produce total rainfall accumulations of 3 to 6 inches with maximum amounts of 10 inches along the coastal sections of the Mexican states of Guerrero, Michoaca, Colima and Jalisco. This rainfall may produce life- threatening flash floods and mudslides. SURF: Swells generated by Lorena will affect portions of the southwest coast of Mexico 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.

NWS National Hurricane Center Miami FL
1100 AM PDT Tue Sep 17 2019

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

The National Hurricane Center is issuing advisories on Hurricane
Kiko, located over the southwestern part of the basin, on newly
formed Tropical Depression Fourteen-E, located several hundred
miles south of the southern tip of the Baja California peninsula,
and on newly formed Tropical Storm Lorena, located a few hundred
miles south-southeast of Zihuatanejo, Mexico.

Disorganized cloudiness and showers located just west of Central
America are associated with a trough of low pressure. Gradual
development of this system is anticipated during the next several
days, and a tropical depression could form over the weekend while
the wave moves westward or west-northwestward at 5 to 10 mph.
Locally heavy rainfall is possible along the coasts of El Salvador,
Guatemala and southeastern Mexico during the next few days.
* Formation chance through 48 hours...low...10 percent.

Issued at 1000 AM CDT Tue Sep 17 2019 000 WTPZ45 KNHC 171456 TCDEP5 Tropical Storm Lorena Discussion Number 1 NWS National Hurricane Center Miami FL EP152019 1000 AM CDT Tue Sep 17 2019 First-light 1-minute visible imagery from GOES-W revealed that the disturbance just south of Mexico has developed a well-defined surface center. The system has also developed an extensive convective band stretching from the southwest to the northeast quadrant of the cyclone. A pair of ASCAT passes overnight showed winds were already at tropical-storm strength, so the system has been designated as Tropical Storm Lorena. The initial intensity is set at 35 kt, though the ASCAT data showed winds could actually already be higher than that, so that may be conservative. Lorena is moving quickly toward the northwest, or 305/13 kt. A mid-level ridge centered over the Gulf of Mexico should keep it moving generally northwestward for the next few days, at a slightly slower speed. Most of the dynamical models show this general scenario, however some of the typically reliable track models, including the GFS, seem to have trouble resolving the small cyclone, and show the cyclone moving more west-northwestward. This small difference is important and could be the difference between Lorena directly impacting Mexico or passing just to the southwest. The NHC forecast is on the far right side of the guidance envelope, favoring the ECMWF and UKMET solutions, which seem to have a more realistic current depiction of the tropical cyclone. The NHC forecast is on the far right side of the standard guidance envelope, but is near the middle of the ECMWF ensemble. This brings Lorena very near the Mexico coast in about 2 days and it is possible that the storm could make landfall. At longer ranges the GFS depicts the beginning of a binary interaction between Lorena and the newly-formed depression to the west, however at the moment this does not seem particularly likely, and the NHC forecast favors the ECMWF through day 5 which shows no such interaction. Moderate easterly shear appears to be affecting the tropical storm for now, and this will likely be the primary moderating factor for Lorena's intensity. SSTs are very warm and there is ample moisture, but only slow intensification is likely as long as the shear persists. The NHC forecast therefore shows slow strengthening for the next couple of days. Beyond that time, if the cyclone moves inland, it should quickly weaken or possibly dissipate, but if it stays farther offshore it may have an opportunity to strengthen further. The NHC forecast holds the cyclone nearly steady-state, but it is well below the consensus at day 4 and 5, since most of the intensity models are based on tracks that stay well offshore of Mexico.

Issued at 900 AM MDT Tue Sep 17 2019 000 WTPZ44 KNHC 171448 TCDEP4 Tropical Depression Fourteen-E Discussion Number 1 NWS National Hurricane Center Miami FL EP142019 900 AM MDT Tue Sep 17 2019 Deep convection has intensified over the small area of low pressure that NHC has been monitoring for several days. Both SAB and TAFB estimates indicate that there is now enough organized thunderstorm activity to initiate advisories on a tropical depression, and the initial wind speed of 30 kt matches the overnight scatterometer data and the subjective Dvorak estimates. The initial motion is an uncertain 335/8 kt, with steering provided by a distant low-level ridge to the east. The cyclone is forecast to gradually turn toward the northwest and west-northwest during the next several days as it runs into the southwestern side of a mid- latitude ridge centered over northwestern Mexico. The biggest complication is Tropical Storm Lorena to the northeast, which some of the model guidance, such as the 6Z GFS, shows a binary interaction with at longer term, which could induce a more northward motion. While I can't rule that out, the forecast will stay closer to the models that show less interaction, such as the more westward HWRF and ECMWF solutions, and the NHC forecast is close to a blend of those models. While almost all of the guidance indicates strengthening of this depression into a hurricane in a few days, this forecast is problematic because of the proximity to Lorena. Convective outflow from Lorena could induce more easterly shear than is currently forecast if the tracks get closer together. For now, since the cyclones are forecast to remain a fair distance from one another, this wind speed prediction assumes that the low-shear environment in most of the models materializes, and the forecast follows the corrected-consensus intensity guidance HCCA.
