NewJersey: The Flash Flood Watch is now in effect for Portions of New Jersey…and Pennsylvania…including the following areas…in New Jersey…Hunterdon, Mercer, Middlesex, Morris, Somerset, Sussex, and Warren. In Pennsylvania…Berks, Carbon, Delaware, Eastern Chester, Eastern Montgomery, Lehigh, Lower Bucks, Monroe, Northampton, Philadelphia, Upper Bucks, Western Chester, and Western Montgomery.
From Wednesday morning through Thursday afternoon. The remnants of Hurricane Ida will pass through the region Wednesday through early Thursday morning. Periods of heavy rain and scattered thunderstorms associated with this low will result in widespread 3 to 5 inches of rain, with locally higher amounts likely exceeding 6 inches by Thursday morning. Combined with wet antecedent conditions, this will lead to numerous instances of flash flooding, some of which may be significant. Flooding of creeks, streams, urban areas, and poor drainage areas is likely in the areas of heaviest rain. Water is likely to cover the roads, especially in low-lying areas. Moderate to major flooding is possible along some main stem rivers, and roads and structures near these rivers may be flooded.
You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
