074 FXUS64 KCRP 261130 AFDCRP Area Forecast Discussion National Weather Service Corpus Christi TX 630 AM CDT Thu Sep 26 2024 ...New AVIATION... .SHORT TERM... (Today through Friday) Issued at 358 AM CDT Thu Sep 26 2024 Key Messages: - Hazardous marine/coastal conditions expected through the weekend Conditions will continue to dry out behind the front yielding highs in the lower 90s today with lows in 60s across the region! Exciting right? We can enjoy that the next couple nights with light and variable winds. In the wake of the front today, winds will be expected to increase along the nearshore and offshore waters through the evening leading to Small Craft Advisory conditions. There after due to 10-12 second period swells associated with Hurricane Helene in the eastern Gulf of Mexico, those Small Craft Advisory conditions will persist mainly in the offshore waters with minor coastal flooding possible during the high tide cycle. With seas remaining agitated the high risk of rip currents will also be extended through the weekend. Be sure to exercise extreme caution if heading out to the beaches. && .LONG TERM... (Friday night through next Wednesday) Issued at 358 AM CDT Thu Sep 26 2024 Key Messages: - Increasing risk of rip currents and potential coastal flooding late this week as Hurricane Helene moves across the Gulf Dry conditions are expected into through the weekend with no significant weather to speak of. Moisture will begin to return early next week, leading to a low chance of showers and thunderstorms over the waters. By midweek, we`ll start to see some showers and thunderstorms over the southern Coastal Plains, mainly due to sea breeze convection. Temperatures will remain in the upper 80s along the coast to the mid 90s over the Brush Country. With the drier air in place, it will feel much more pleasant with only a minor risk of heat related impacts. Overnight temperatures will be quite a bit cooler, with lows in the 60s. Effects from Hurricane Helene will linger into the weekend as 10-12s swells reach our coastline. This will likely lead to some minor coastal flooding during times of high tide as well as an increased risk of rip currents. These conditions will begin to diminish Saturday night and Sunday though they could linger a bit. Confidence in minor coastal flooding is moderate to high on Saturday but by Sunday, confidence is low. && .AVIATION... (12Z TAFS) Issued at 606 AM CDT Thu Sep 26 2024 Skies will be mostly clear today with VFR conditions prevailing through the TAF period across all sites. Winds are expected to increase throughout the region late this morning into the afternoon gusting to around 15-20 knots. This will diminish this evening becoming light and variable tonight. && .MARINE... Issued at 358 AM CDT Thu Sep 26 2024 Moderate to strong offshore flow is expected this morning in response to a passing frontal boundary. A Small Craft Advisory is in effect across the near and offshore waters north of Port Aransas. Waves are expected to become elevated offshore this afternoon in response to Hurricane Helene progressing through the Gulf, leading to Advisory conditions in the Gulf waters south of Port Aransas which will likely persist through Saturday. Flow will transition to weak to moderate this evening allowing the nearshore waters to likely drop back to Small Craft Should Exercise Caution conditions. Long period swell and elevated seas from Hurricane Helene will linger into the weekend before subsiding Saturday night. Low rain chances will gradually increase to moderate, mainly over the offshore waters, through the middle of next week as moisture returns. && .PRELIMINARY POINT TEMPS/POPS...
