Key Factors
- 01 Flood Watch is in effect from 2:33 AM EDT until 2:00 PM EDT (through 14:00), with flash flooding possible from excessive rainfall; heavy rainfall can quickly make roads unsafe.
- 02 Hourly forecast shows increasing thunderstorm chances from about 1–2 PM onward, peaking from roughly 6–11 PM (probability of precipitation ~72% to 89%) with likely showers and thunderstorms.
- 03 Daily forecast indicates some storms could produce heavy rain (today 1 PM–5 PM and then showers/thunderstorms likely).
- 04 Wind is light (generally 1–6 mph), so crosswind risk is not the main issue; the main risk is water on the roadway and reduced traction.
- 05 Heat Advisory runs until 8:00 PM EDT (heat index 95–100), which can increase driver fatigue/health risk during long exposure, especially in stopped traffic.

Recommendation
Use the morning slot only: drive between 7:00–10:00 AM EDT when precipitation chances are low (around 6–8%) and conditions are mostly cloudy. For the evening, delay travel as much as possible and only drive between 8:00–9:00 PM EDT when thunderstorm chances are still high but slightly lower than the peak hours (about 71–74%); avoid earlier evening and any travel during periods of active downpours.
