Key Factors
- 01 Flash Flood Warning (Severe, Immediate) for Northern Bergen, Northwestern Essex and Passaic Counties until 8:00 AM EDT, with 1-3 inches of rain already fallen and roads, underpasses and streets flooding
- 02 Flood Watch through 11 PM EDT for much of NJ, northern DE and eastern PA; rainfall rates of 1-3 inches per hour and localized totals of 3-5 inches possible
- 03 Showers and thunderstorms likely 7-11 AM (precip chance 69-94%), then again 2-5 PM (about 62-63%), with a 40-51% chance in between
- 04 Additional 1-2 inches of rain possible today; river and stream flooding and poor drainage areas are at risk
- 05 Southwest gusts up to 21 mph are a minor factor; heavy rain, hydroplaning and reduced visibility are the main concerns
- 06 Temperatures are 74-82F, so ice is not a concern
- 07 Visibility data is not provided, so reduced visibility in downpours is inferred from the heavy rain

Recommendation
Avoid driving during the morning storms and do not enter flooded roads (turn around, don't drown). If travel is necessary, the best morning window is roughly 11 AM-1 PM, when rain chances are lower (43-51%), but check radar and local road closures first. The safest evening window is 7-10 PM, when precipitation chances drop to 5% or less, though some roads may still be flooded or debris-covered.
