Key Factors
- 01 Flash Flood Warning (NWS Upton) until 8:00AM EDT with ongoing roadway flooding and 1-3 inches already fallen
- 02 Flood Watch until 11:00PM EDT; rainfall rates of 1-3 inches per hour possible, localized totals 3-5 inches
- 03 Hourly precipitation chances 85-94% from 8AM-11AM and 62-63% from 2PM-5PM, thunderstorms with heavy downpours reducing visibility and traction
- 04 Wind gusts to 21 mph with storms; brief gusty outflow possible during thunderstorms
- 05 Rivers, streams, urban and poor-drainage areas already running high, so even modest additional rain can flood roads
- 06 No visibility data provided, so reduced-visibility impacts in downpours are estimated

Recommendation
Avoid non-essential driving today, especially 7AM-11AM and 2PM-5PM. If you must drive, the safest morning window is roughly 11:00AM-1:00PM (lower ~40-50% storm chance) and the safest evening window is after 7:00PM, when rain chances drop to 5% or less and skies clear. Never drive through flooded roads or underpasses - turn around, don't drown - and allow extra following distance for standing water and hydroplaning.
