Key Factors
- 01 Flood Watch (Severe) issued 2:16 AM EDT valid through late tonight; flash flooding possible in urban and poor-drainage areas
- 02 Rainfall rates potentially 1-2 inches per hour, with storm totals of 1-2 inches during the day and another 1-2 inches overnight
- 03 Thunderstorm probability climbs from 55% at 11 AM to 99% by 6-8 PM; some storms could be severe
- 04 Heavy rain reduces visibility and causes hydroplaning on standing water
- 05 East winds 5-14 mph with gusts to 25 mph, plus stronger erratic gusts possible in thunderstorms
- 06 No explicit visibility data provided, so visibility impacts are inferred from heavy rain rather than measured

Recommendation
Avoid non-essential travel from about 2 PM through the overnight hours, when thunderstorms and flash flooding are most likely. Safest morning window is roughly 7:00-10:00 AM (light rain chances, 14-30%). There is no low-risk evening window; if you must drive in the evening, the least-bad slot is around 9:00-11:00 PM as winds ease, but rain remains near 90% - never drive through flooded roadways, allow extra following distance, and use headlights.
