Key Factors
- 01 Flood Watch (severe) for excessive rainfall: 1-2 inches expected, localized 3-5 inches, rates up to 1-3 inches per hour in strong storms
- 02 Precipitation chance rises to 85% from 2pm-5pm and stays around 80% until about 8pm, with thunderstorms throughout
- 03 Morning storms possible from 8am-11am (27-56% chance), so there is no fully dry window
- 04 Flooding likely in poor drainage and urban areas; reduced visibility and hydroplaning risk in heavy downpours
- 05 Patchy fog and more storms possible from 1am-5am tonight
- 06 Winds are light (under 10 mph) and temperatures are warm (67-83F), so wind and ice are not concerns
- 07 Data discrepancy: the alert text says the watch starts at noon, but the alert window field ends at 12:00pm, so the exact timing is uncertain

Recommendation
Avoid non-essential driving today. If you must drive, the best windows are early morning around 7:00-8:00am, before storms build (5% chance at 7am), and late evening around 9:00-10:00pm, when rain chances are lowest (about 31-37%) and rates should be weaker, though showers are still possible. Avoid 2pm-8pm, never drive through flooded roads, and check for Flash Flood Warnings before leaving.
