Key Factors
- 01 Flood Watch in effect from 2 PM today through Monday evening; rain rates over 2 inches per hour possible, bringing flash flooding risk in low-lying, poor-drainage, and urban areas
- 02 Precipitation chances rise from 21% at 1 PM to 48% by 4 PM, 61-74% from 5-10 PM, and peak at 89% around 10-11 PM
- 03 Tonight's forecast calls for 1 to 2 inches of rain, with heavy downpours likely reducing visibility and raising hydroplaning risk
- 04 Thunderstorms bring lightning risk; winds stay light (1-6 mph) and no gust data is provided
- 05 Heat Advisory 8 AM-8 PM (heat index 95-100); vehicle breakdowns or being stranded in the heat pose a health risk
- 06 No visibility data is provided, and the alert time fields are inconsistent with the alert descriptions, which adds some uncertainty

Recommendation
Best morning window is 7 AM to 12 PM, when conditions are dry (6-13% rain chance) and winds are calm. Complete trips before 1 PM if possible. There is no reliably safe evening slot, since storm chances stay at 61-89% from 5 PM to midnight. If you must drive in the evening, the least risky window is about 1-4 PM, before the 5 PM rise in storm chances. After that, delay non-essential trips, never drive through flooded roads, and monitor for Flash Flood Warnings. Carry water and keep A/C working because of the heat.
