DISCUSSION...Convection is beginning to develop near the higher terrain of southern/central UT and northern AZ at midday as lower elevation temperatures warm into the 60s and 70s. Thunderstorms should slowly increase in coverage and intensity over the next few hours. Effective shear magnitudes around 25-35 kt and steepening low/midlevel lapse rates will support at least periodically organized cells, with some high-based supercell structures possible. Meager boundary-layer moisture will limit instability, resulting in transient stronger cells through the afternoon. Sporadic severe hail and strong outflow gusts will be possible as convection shifts east/northeast. Given the transient and isolated nature of any more intense convection, a watch is not expected at this time. ..Leitman/Guyer.. 10/02/2022 ...Please see www.spc.noaa.gov for graphic product...

Preparations to protect life and property should be rushed to completion. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, generally within 36 hours. A Hurricane Watch means that hurricane conditions are possible within the watch area. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Interests elsewhere along the coast of western and northwestern Mexico should monitor the progress of Orlene. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 1200 PM MDT (1800 UTC), the center of Hurricane Orlene was located near latitude 19.9 North, longitude 106.9 West. Orlene is moving toward the north near 8 mph (13 km/h). A turn toward the north-northeast is expected later today. On the forecast track, the center of Orlene should pass near or over Las Islas Marias tonight or Monday morning, and reach the coast of mainland Mexico within the warning area later on Monday or Monday night. Maximum sustained winds are near 115 mph (185 km/h) with higher gusts. Orlene is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Weakening is expected during the next day or so, however Orlene is forecast to be a strong hurricane when it passes near or over the Islas Marias, and remain a hurricane when it reaches southwestern Mexico. Hurricane-force winds extend outward up to 15 miles (30 km) from the center and tropical-storm-force winds extend outward up to 70 miles (110 km). The latest minimum central pressure estimated from Air Force Reserve reconnaissance aircraft data is 972 mb (28.70 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are expected in Las Islas Marias tonight, with tropical storm conditions beginning later today. Hurricane conditions are expected in the warning area along the coast of mainland Mexico late Monday, with tropical storm conditions beginning early Monday. Tropical storm conditions are expected to spread northward in the tropical storm warning area today through early Monday. Hurricane conditions are possible along the coast of mainland Mexico within the hurricane watch area by tonight or early Monday. Tropical storm conditions are possible within the tropical storm watch area today. RAINFALL: Orlene is expected to produce the following rainfall across portions of Southwest Mexico through Tuesday: * Islas Marias: 6 to 10 inches, with local amounts of 14 inches. * Nayarit and Sinaloa: 3 to 6 inches with local amounts of 10 inches. * Jalisco and Colima: 1 to 3 inches with local amounts of 5 inches. These rainfall amounts will likely lead to flash flooding, as well as possible landslides in areas of rugged terrain. STORM SURGE: A dangerous storm surge is likely to cause coastal flooding along the coast of mainland Mexico in the warning area in regions of onshore winds. SURF: Large swells generated by Orlene are affecting the west coast of Mexico and will spread northward to the southern portion of the Baja California peninsula and the Gulf of California over the next couple of days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 300 PM MDT. $$ Forecaster Brown

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1222 PM CDT Sun Oct 02 2022 Valid 031200Z - 041200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Organized severe thunderstorms are not forecast for Monday across the contiguous United States. ...Synopsis... A weak mid- to upper-level trough will migrate slowly east across MT/WY into the Dakotas through Tuesday morning. A surface trough will extend from the Dakotas southward into the central High Plains while high pressure influences weather conditions across much of the central and eastern U.S. Near the surface trough, a narrow plume of modest moisture (surface dewpoints in the 40s and lower 50s) and heating will yield MLCAPE around 750 J/kg from SD into NE along the wind shift, beneath relatively weak midlevel southwesterlies below 30 kt. Scattered convection is likely to form off the Front Range, producing small hail and locally gusty winds. Given the relatively dry air mass and weak low-level winds, it appears convection will be sub severe. Farther southwest in the Four Corners, primarily diurnal storm activity will result in widely scattered to scattered storms during the afternoon to early evening. ..Smith.. 10/02/2022 Read more

Isolated severe hail and wind-producing storms may occur from Utah northeastward into the northern High Plains this afternoon and early evening. ...Utah/Four Corners to northern High Plains... A closed upper low centered over southern Montana will gradually open and spread slowly eastward, with a southern peripheral belt of moderately strong westerlies over the Great Basin and central Rockies. A few areas of showers/thunderstorms are ongoing early today, but in general, relatively cloud-free skies will allow for ample early autumn heating and related boundary layer destabilization this afternoon from southern/eastern Utah into southern/eastern Wyoming and the nearby High Plains areas including the Black Hills vicinity. Destabilizing boundary layer aside, the right-entrance region of a cyclonically curved mid-level jet will influence thunderstorm development particularly across southern/eastern Utah. The strength of mid/high-level west-southwesterly winds (35+ kt effective shear) could yield some high-based supercells aside from sustained multicells. Severe hail and severe-caliber winds gusts can be expected on an isolated basis. Other storms will also increase over the mountains/interior Wyoming and move into eastern Wyoming/western South Dakota vicinity later this afternoon. Meager low-level moisture will limit CAPE and overall updraft strength. However, moderately strong winds aloft and steep lapse rates will promote gusty winds and perhaps some hail in the strongest storms. ..Guyer/Wendt.. 10/02/2022 Read more

Hurricane Orlene Forecast Discussion Number 16

2 years 11 months ago
Issued at 900 AM MDT Sun Oct 02 2022 000 WTPZ41 KNHC 021446 TCDEP1 Hurricane Orlene Discussion Number 16 NWS National Hurricane Center Miami FL EP162022 900 AM MDT Sun Oct 02 2022 The satellite presentation of Orlene has degraded since early this morning. It appears that an increase in southwestern shear may have begun, as the eye has become cloud filled. Subjective satellite classifications from TAFB and SAB were T5.5 (102 kt), and objective estimates range from 112 to 120 kt. Based on the degraded satellite presentation, the initial intensity has been reduced to 110 kt. An Air Force Reserve reconnaissance aircraft is currently en route to investigate the hurricane, and should provide additional information on the strength and size of the wind field early this afternoon. Orlene has likely peaked in intensity. Although the sea surface temperatures remain warm along the forecast track, increasing southwesterly vertical wind shear during the next 24 to 36 hours is likely to cause the small hurricane to weaken. However, Orlene is forecast to pass near or over the Islas Marias as a strong hurricane late tonight or early Monday, and reach the coast of mainland Mexico has a hurricane by late Monday or Monday night. After landfall, rapid weakening is expected and the low-level center should dissipate over the mountainous terrain of southwestern Mexico in 60-72 hours. Orlene has continued to move just east of due north or 005/7 kt. The hurricane is being steered between a mid-level ridge to its east and a broad trough over northwestern Mexico. These steering currents should cause Orlene to bend north-northeastward later today and it should then continue on that general heading until landfall in southwestern Mexico. The latest NHC track forecast is slightly west of the previous advisory, and lies close to a blend of the GFS and ECMWF models (GFEX). This is a little to the right of the other simple and corrected consensus models. The GFS remains significantly farther right and faster than the remainder of the guidance. Key Messages: 1. Hurricane conditions are expected in the Islas Marias tonight, with tropical storm conditions beginning today. A Hurricane Warning is in effect for a portion of west-central mainland Mexico, where hurricane conditions are expected on Monday with tropical storm conditions beginning early Monday. Preparations to protect life and property should be rushed to completion. 2. Heavy rainfall from Orlene is expected to lead to flash flooding, as well as possible landslides in areas of rugged terrain of southwestern Mexico into Tuesday.

A warning is typically issued 36 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, generally within 36 hours. 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. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Interests elsewhere along the coast of western and northwestern Mexico should monitor the progress of Orlene. Additional watches or warnings will likely be required for portions of these areas later today or tonight. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 1200 PM MDT (1800 UTC), the center of Hurricane Orlene was located near latitude 17.8 North, longitude 107.0 West. Orlene is moving toward the north near 5 mph (7 km/h). A north-northeastward motion at a slightly faster speed is expected to begin by tonight and continue through early next week. On the forecast track, the center of Orlene should pass near or over Las Islas Marias Sunday night or Monday morning and reach the coast of mainland Mexico later on Monday or Monday night. Maximum sustained winds are near 75 mph (120 km/h) with higher gusts. Strengthening is expected through Sunday. After that, steady weakening is expected to begin by Sunday night. An Air Force Reserve Hurricane Hunter aircraft is currently enroute to investigate Orlene. Orlene remains a small tropical cyclone. Hurricane-force winds extend outward up to 10 miles (20 km) from the center and tropical-storm-force winds extend outward up to 45 miles (75 km). The estimated minimum central pressure is 989 mb (29.21 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are expected in Las Islas Marias Sunday night, with tropical storm conditions possible by late Sunday. Tropical storm conditions are expected in the tropical storm warning area by early Sunday. Hurricane conditions are possible along the coast of mainland Mexico within the hurricane watch area by Sunday night into Monday. Tropical storm conditions are possible along the coast of mainland Mexico within the tropical storm watch area tonight and Sunday. RAINFALL: Into Monday evening, Orlene is expected to produce 3 to 5 inches of rainfall, with local amounts of 10 inches, for portions of Southwest Mexico. These rainfall amounts should lead to flash flooding, as well as possible landslides in areas of rugged terrain. STORM SURGE: Coastal flooding is likely along the coast of Mexico in the warning area in regions of onshore winds. SURF: Large swells generated by Orlene will affect the coast of southwestern Mexico, and the extreme southern portion of the Baja California peninsula through this weekend. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
