Hurricane PATRICIA Forecast Discussion Number 11
2015-10-22 22:34:17| National Hurricane Center (East Pacific)
Issued at 400 PM CDT THU OCT 22 2015 000 WTPZ45 KNHC 222034 TCDEP5 HURRICANE PATRICIA DISCUSSION NUMBER 11 NWS NATIONAL HURRICANE CENTER MIAMI FL EP202015 400 PM CDT THU OCT 22 2015 Patricia has an impressive satellite presentation, with a small 10 n mi wide eye surrounded by convective cloud tops of -80C to -90C. The NOAA Hurricane Hunter Aircraft found that the pressure had fallen to about 953 mb on their final pass through the center, after indicating earlier that the intensity had increased to 115 kt, which remains the intensity for this advisory. Further strengthening is indicated by much of the intensity guidance given that the shear remains low and the hurricane is over SSTs of 30-31C. The official forecast shows the cyclone peaking at 135 kt in 12 hours, followed by a little weakening prior to landfall as the shear increases, and this is close to the latest intensity consensus aids. Patricia could also undergo an eyewall replacement cycle before landfall that could result in fluctuations in intensity not shown here. After landfall, the hurricane should quickly weaken over the high terrain and dissipate by 72 hours. The hurricane has begun turning a bit more poleward and slowed down during the past few hours, with an initial motion estimate of 300/11. The track forecast reasoning remains unchanged, with Patricia expected to turn northwestward and then northward during the next 24 hours as it moves around the periphery of a mid-level high centered over the Gulf of Mexico. The hurricane is then forecast to accelerate north-northeastward between the high and an amplifying trough over northwestern Mexico. The new NHC track is again a bit to the left of the previous one and is close to the new GFS/ECMWF consensus along on the western side of the guidance envelope. Based on the latest forecast, the government of Mexico has extended the hurricane warning north of Cabo Corrientes to San Blas, which includes the Puerto Vallarta area. Model guidance continues to suggest that the mid-level remnants and moisture from Patricia will be absorbed by a non-tropical area of low pressure that forms over south Texas or the northwestern Gulf of Mexico this weekend. This moisture could contribute to a major rainfall event already ongoing across portions of Texas. For more information, please refer to products from your local National Weather Service office and the NOAA Weather Prediction Center. KEY MESSAGES: 1. Confidence is increasing that Patricia will make landfall in the hurricane warning area along the coast of Mexico as an extremely dangerous major hurricane Friday afternoon or evening. Preparations to protect life and property in the hurricane warning area should be completed today, as tropical storm conditions will begin to affect the warning area tonight or early Friday. 2. In addition to the coastal impacts, very heavy rainfall is likely to cause life-threatening flash floods and mud slides in the Mexican states of Jalisco, Colima, Michoacan and Guerrero beginning late tonight and continuing into Saturday.

Hurricane PATRICIA Forecast Discussion Number 10
2015-10-22 19:59:48| National Hurricane Center (East Pacific)
Issued at 100 PM CDT THU OCT 22 2015 000 WTPZ45 KNHC 221759 TCDEP5 HURRICANE PATRICIA SPECIAL DISCUSSION NUMBER 10 NWS NATIONAL HURRICANE CENTER MIAMI FL EP202015 100 PM CDT THU OCT 22 2015 This Special Advisory updates the initial and forecast intensity of Patricia, based on a recent NOAA Hurricane Hunter aircraft SFMR observation of 114 kt. The aircraft reported that the central pressure was around 958 mb. Some of the wind radii have also been adjusted outward. This Special Advisory replaces the 1800 UTC intermediate advisory. The environment is expected to be conducive for continued strengthening in the next 24 hours, with the cyclone in an area of very low shear and SSTs above 30C. Some slight weakening is shown on Friday prior to landfall, as southwesterly shear begins to increase, and Patricia could undergo an eyewall replacement cycle. After landfall, Patricia should rapidly weaken, and the low-level circulation should dissipate over the high terrain of Mexico before 72 hours. No change was made to the track forecast from the previous advisory. KEY MESSAGES: 1. Confidence is increasing that Patricia will make landfall in the hurricane warning area as an extremely dangerous major hurricane Friday afternoon or evening. Preparations to protect life and property in the hurricane warning area should be completed today, as tropical storm conditions will begin to affect the warning area tonight or early Friday.

Hurricane PATRICIA Forecast Discussion Number 9
2015-10-22 16:42:17| National Hurricane Center (East Pacific)
Issued at 1000 AM CDT THU OCT 22 2015 000 WTPZ45 KNHC 221442 TCDEP5 HURRICANE PATRICIA DISCUSSION NUMBER 9 NWS NATIONAL HURRICANE CENTER MIAMI FL EP202015 1000 AM CDT THU OCT 22 2015 Patricia continues to strengthen, with an eye evident in recent microwave images and intermittently seen in infrared imagery. The initial intensity is set to 85 kt, a bit above the latest UW-CIMSS ADT estimate of T4.7/82 kt, and this could be a little conservative if the eye becomes more distinct in infrared imagery. Even so, Patricia has intensified 50 kt in the last 24 hours. A NOAA Hurricane Hunter aircraft will investigate Patricia later today and provide valuable information on the intensity and structure of the hurricane. The environment is expected to be conducive for continued rapid strengthening in the next 24 hours, with the cyclone in an area of very low shear and SSTs above 30C. In fact, the SHIPS RI index shows a 95 percent chance of a 40-kt increase in the next 24 hours. The official forecast is close to the upper end of the guidance near the LGEM, and shows Patricia reaching major hurricane status by this evening and continuing to intensify through Friday morning. Little change in intensity is forecast on Friday prior to landfall, as southwesterly shear begins to increase. After landfall, Patricia should rapidly weaken, and the low-level circulation should dissipate over the high terrain of Mexico before 72 hours. The hurricane continues to move quickly west-northwestward, with an initial motion estimate of 295/15. The track forecast philosophy has not changed, with Patricia expected to turn northwestward and then northward during the next 24 hours as it moves around the periphery of a mid-level high centered over the Gulf of Mexico. Then, the hurricane should turn north-northeastward between the high and an amplifying trough over northwestern Mexico. The new NHC track has again been shifted a little to the left to account for the initial motion and is near the latest GFS/ECMWF consensus on the western side of the guidance envelope. Based on the latest forecast, the government of Mexico has issued a hurricane watch and a tropical storm warning from north of Cabo Corrientes to San Blas, which includes the Puerto Vallarta area. Note that model guidance suggests that the mid-level remnants and moisture from Patricia will be absorbed by a non-tropical area of low pressure that forms over south Texas or the northwestern Gulf of Mexico this weekend. This moisture could contribute to a major rainfall event already ongoing across portions of Texas.
