059 FXUS64 KCRP 050514 AFDCRP Area Forecast Discussion National Weather Service Corpus Christi TX 1214 AM CDT Fri Jul 5 2024 ...New AVIATION... .SHORT TERM... (Tonight through Friday night) Issued at 405 PM CDT Thu Jul 4 2024 Key Message: - Moderate risk of heat-related impacts Friday with heat index values 105-110 - High risk of rip currents likely beginning Friday night with swell periods over 12 seconds We`ll have northeasterly flow aloft with Beryl over the Yucatan Peninsula Friday into Friday night and moisture will be above normal (near 2.0"). However, there won`t be much lift support to initiate any convection and therefore have left very low rain chances at less than 10%. Temperatures will remain very warm tomorrow with highs from the 90s to around 100 over the Brush Country under mostly sunny skies. Heat index values will range from 105-110. Swell periods will increase drastically late Friday night and lead to significant wave runup and dangerous swimming conditions. There will likely be a HIGH risk of rip currents in effect beginning either Friday night or Saturday and continuing through the Holiday Weekend into early next week. && .LONG TERM... (Saturday through next Wednesday) Issued at 405 PM CDT Thu Jul 4 2024 Key Messages: - All of South Texas interests should make sure their preparedness plans are in order and stay informed regarding Beryl. - Rain chances increase Sunday night and continue into next week. - Hazardous marine conditions continue this weekend into next week The long term will focus on Hurricane Beryl, and the uncertainty with it. As Beryl approaches South Texas, rain chances are expected expected to increase Sunday along with strong winds most likely arriving Sunday night into Monday. However, the time of arrival of winds and rain is still fluid depending on the actual track of Hurricane Beryl and it`s forward speed after is exits the Yucatan Peninsula tomorrow afternoon. As Hurricane Beryl eventually impacts South Texas, we can expect locally heavy rain with current estimated forecast rainfall amounts between 7-9" from the Coastal Plains to the Victoria Crossroads and 3-6" across the Brush Country Saturday night through Wednesday night. Therefore, South Texas is currently under a Marginal Risk of Excessive Rainfall Sunday and Sunday night and a Slight Risk Monday and Monday night. Expect rainfall forecast rainfall amounts and excessive rain outlooks to continue changing in the coming days as we gain better confidence. Another hazard that will be elevated will be out tornado threat. Due to the angle of approach, increase friction will enhance the environmental conditions for tornadoes across the eastern half of the storm. As for marine hazards, they are expected to begin earlier than the arrival of the Hurricane. High risk of rip currents are expected to begin in the short term forecast and continue into this weekend. Apart from rip currents, coastal flooding is expected to impact the barrier islands this weekend due to swell periods of 12-14 seconds and swell heights of 3-4 feet ahead of the storm. Please continue to check back frequently for updates. && .AVIATION... (06Z TAFS) Issued at 1210 AM CDT Fri Jul 5 2024 VFR conditions expected through the TAF period. A brief period of MVFR conditions will be possible between 10-14Z for COT and LRD due to CIGs, Light south to southeast winds overnight will become gusty Friday afternoon with gusts around 20KT, then light again Friday night. && .MARINE... Issued at 405 PM CDT Thu Jul 4 2024 Weak to moderate south to southeasterly winds will continue through Sunday morning, gradually increasing throughout the day as Hurricane Beryl approaches. While uncertainty is still high on timing and actual track, elevated seas up to 12 feet occasionally to 15 feet can be expected late this weekend with strong winds as Beryl approaches South Texas. Rain chances will increase Sunday night with high chances of rain hanging around through Tuesday of next week. && .PRELIMINARY POINT TEMPS/POPS...
