Catastrophic Flooding Impacts in South-Central Texas

Widespread life-threatening flash and urban flooding will continue to pose a significant threat to life and property in south-central Texas. Catastrophic fiver flooding, with rapid rises on small streams, arroyos, and typically dry washes, is expected. Monsoonal showers persist across the Great Basin and Southwest with greatest flash flooding in southern Arizona. Read More >

Aviation Forecast Discussion

.AVIATION... 06Z TAFS: There is a 30-40% chance for showers and thunderstorms to impact KGEG-KSFF-KCOE through 14Z as elevated showers and thunderstorms take advantage of elevated instability. Other TAF sites have less than a 30% chance, so have kept a PROB30/TEMPO out for now. Confidence is low for gusty outflows tonight but may reach 30 mph. VFR conditons will prevail with fairly light winds outside of the Cascade gaps Friday evening in central WA. FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: High confidence in VFR conditions. Low confidence for gusty outflow winds. ----------------------- Confidence descriptors: Low - Less than a 30 percent chance Moderate - 30 to 70 percent chance High - Greater than a 70 percent chance For additional probabilistic information for NWS Spokane airports, please refer to the Aviation Dashboard on our webpage: https:/www.weather.gov/otx/avndashboard &&
