A Flash Flood Warning is in effect through 10:00 AM EDT with heavy thunderstorms and 1–2+ inches of rain possible this morning; hazardous driving (flooded roads/underpasses) is likely in the warned area. Conditions improve after midday with showers ending and partly sunny skies, making travel safer in the afternoon/evening.
- 01 Active Flash Flood Warning (severe) until 10:00 AM EDT with radar/ gauges indicating heavy rainfall and expected rates of 1–2 in/hr and additional 0.5–1 in — flash flooding of roads/underpasses is ongoing or expected.
- 02 Flood Watch until 12:00 PM EDT; high probability of showers/thunderstorms from 7:00–11:00 AM (PoP 62–85%) increasing runoff and localized flooding.
- 03 Hourly temps are well above freezing and winds are light, so ice is not a concern; the primary hazard is flooding of roadways and reduced drivability in low-lying/urban areas.
Avoid driving during the hazardous morning window: do not travel between 7:00 AM and 10:00 AM EDT (flash flooding ongoing). Safer travel windows: morning (if necessary) — delay to after 12:00 PM to 1:00 PM EDT when showers subside; evening — 6:00 PM to 8:00 PM EDT when skies are partly cloudy and precipitation chance is very low. If you must drive during or shortly after heavy rain, avoid low-lying roads and underpasses and do not attempt to drive through flooded areas.
