Key Factors
- 01 Flash Flood Warning in effect until 8:00 AM EDT for northern Bergen, northwestern Essex, and Passaic counties, with 1-3 inches of rain already fallen and roadway flooding still receding
- 02 Flood Watch through 11:00 PM EDT with possible rainfall rates of 1-3 inches per hour and localized totals of 3-5 inches
- 03 Showers and thunderstorms 8-11 AM with 85-94% precipitation chance, the worst period of the day
- 04 A second round of storms is likely 2-5 PM (62-63% chance), with 40-52% chances in between and until 6 PM
- 05 Flooded highways, streets, and underpasses, reduced visibility in heavy rain, and lightning risk
- 06 Winds are light (8-10 mph, gusts to 21 mph), so wind is not a major factor
- 07 Rain chances fall to 20% at 6 PM and 0-5% from 7 PM onward, though standing water may linger
- 08 Visibility data are not provided, and the alert time fields appear inconsistent (the 'to' times match the issue times), so the effective windows are taken from the headlines

Recommendation
Avoid non-essential driving before 11 AM and between 2 PM and 6 PM. The best morning window is roughly 11 AM to 1 PM, when rain chances dip to 40-51%, but storms remain possible, so check radar first. The best evening window is 7 PM to 11 PM, when conditions are mostly dry and winds are calm. Watch for lingering flooded roads and underpasses, and never drive through standing water: turn around, don't drown.
