Key Factors
- 01 Flood Watch (severe) for flash flooding due to excessive rainfall: from 2 PM EDT this afternoon through late tonight (until June 23 at 6:00 AM EDT).

- 03 Storm impacts: daily forecast notes some storms could be severe and produce heavy rain, with 1–2 inches possible (also 1–2 inches possible overnight).
- 04 Reduced driving safety likely in flooded/poor drainage and urban areas (Flood Watch impacts), especially during the peak heavy-rain window from mid/late afternoon into night.

Recommendation
Try to avoid driving during the worst period. If you must travel, the safer window is in the morning before storms intensify: 7:00–10:00 AM EDT (showers chance remains 14–30%). For the evening, do not drive during the Flood Watch’s peak heavy-rain period: avoid 2:00–11:00 PM EDT; if travel is unavoidable, wait as late as possible after heavy storms ease and continue to monitor for updates/flash-flood warnings.
