Key Factors
- 01 Flood Watch in effect 2:16 AM to 2:00 PM EDT (NWS effective window shown as through 14:00) for flash flooding from heavy rainfall rates of 1-2 in/hr
- 02 Precipitation chance rises from 14% at 7am to 55-99% from midday through evening
- 03 Showers and thunderstorms likely/likely-severe with heavy rain, reducing visibility and causing hydroplaning risk
- 04 Rainfall totals of 1-2 inches expected, increasing urban/poor-drainage flooding risk
- 05 Wind gusts up to 25 mph possible during storms, adding crosswind risk for high-profile vehicles
- 06 Storms may turn severe per daily forecast, which can bring sudden intense downpours and lightning

Recommendation
If travel is necessary, drive earliest in the morning between 7:00-8:00 AM when precipitation chance is lowest (14%) before showers develop; avoid midday through night. There is no truly safe evening window since storms are likely 90-99% probability from 6 PM through midnight - if evening travel is unavoidable, wait for a lull between storm cells and avoid flooded roadways, never drive through standing water.
