000 ABPZ20 KNHC 032306 TWOEP Tropical Weather Outlook NWS National Hurricane Center Miami FL 500 PM PDT Wed Jul 3 2024 For the eastern North Pacific...east of 140 degrees west longitude: Offshore of Southern Mexico (EP91): Showers and thunderstorms associated with a broad area of low pressure located a few hundred miles south of the southern coast of Mexico continue to show signs of organization. Environmental conditions appear conducive for some further development of this system during the next day or so, and a short-lived tropical depression could form during that time. On Friday, the system is forecast to move over cooler waters and development after that time is not expected. The disturbance is forecast to move northward to northwestward at 10 to 15 mph, remaining offshore of the southwestern coast of Mexico. * Formation chance through 48 hours...medium....60 percent. * Formation chance through 7 days...medium...60 percent. $$ Forecaster Hagen/Cangialosi

Hurricane Beryl Forecast Discussion Number 21
2024-07-03 22:47:41| National Hurricane Center (Atlantic)
Issued at 500 PM EDT Wed Jul 03 2024 281 WTNT42 KNHC 032047 TCDAT2 Hurricane Beryl Discussion Number 21 NWS National Hurricane Center Miami FL AL022024 500 PM EDT Wed Jul 03 2024 While westerly shear continues to affect Beryl, the central core of the hurricane has made a bit of a comeback this afternoon with the eye becoming better defined in Cuban radar data and re-appearing in satellite imagery. Whether this has resulted in any re-intensification is unclear, so the initial intensity will be held at 120 kt pending the arrival of the next reconnaissance aircraft. The Cuban radar data shows that northern eyewall is brushing the southern coast of Jamaica at this time, with hurricane conditions occurring mainly on the south side of the island. The initial motion is now 285/17. A strong mid-level ridge centered over the southeastern US is expected to continue steering Beryl generally west-northwestward at a decreasing speed for the next couple of days or so. The motion should bring the center near or just south of Jamaica during the next few hours and south of the Cayman Islands tonight. After that, the system should reach the Yucatan Peninsula of Mexico in 36-48 h and emerge over the southwestern Gulf of Mexico by 60 h. Once over the Gulf, Beryl should turn northwestward toward a break in the subtropical ridge caused by a large mid-latitude trough over the central United States. There is a bit better agreement in the track guidance this cycle, as the GFS has shifted its track a little southward and the ECMWF has shifted its track a little northward. Based on this and other guidance, the 96- and 120-h points have been shifted a little to the southwest of the previous forecast. However, there is still uncertainty during this part of the forecast, and a landfall in Texas cannot yet be ruled out. Beryl should continue to experience some westerly shear for the next 24 h, and the ECMWF forecasts moderate shear to persist until the hurricane makes landfall in Yucatan. This portion of the intensity forecast calls for weakening as shown by the guidance. However, given that Beryl seems reluctant to weaken, the forecast is near the upper edge of the intensity guidance. The cyclone should weaken to a tropical storm while crossing Yucatan. The intensity guidance has become less enthusiastic about the potential for Beryl to re-intensify over the Gulf of Mexico. However, the model forecast upper-level winds seem generally favorable, and based on this the intensity forecast continues to call for Beryl to re-gain hurricane strength over the Gulf. Key Messages: 1. Devastating hurricane-force winds, life-threatening storm surge, and damaging waves are expected to continue in Jamaica over the next several hours and spread into the Cayman Islands tonight. Mountainous locations in Jamaica are likely to experience destructive wind gusts. 2. Life-threatening flash flooding and mudslides from heavy rainfall are expected over much of Jamaica and southern Haiti through today. 3. Damaging winds, a dangerous storm surge, and heavy rainfall are expected over portions of the Yucatan Peninsula and Belize beginning Thursday night as Beryl approaches that area as a hurricane. Hurricane and Tropical Storm Warnings are now in effect for portions of that area. 4. There remains uncertainty in the track and intensity forecast of Beryl over the western Gulf of Mexico this weekend. Interests in the western Gulf of Mexico, including southern Texas, should monitor the progress of Beryl.
