The National Weather Service in Mount Holly, N.J., has expanded a flood watch to include portions of Delaware, Northeast Maryland and New Jersey, including the Delaware beaches and inland Sussex County from Thursday morning through Friday morning.
Heavy rain is expected again across the watch area. Rain should begin tonight. However, the heaviest rainfall is expected to occur during the day Thursday into Thursday night. Storm total amounts should average 1.5 to 2.5 inches, with localized higher amounts probable.
The estimated rainfall amounts will cause flooding of low-lying areas, as well as causing streams and creeks to rise out of their banks. Many rivers and streams remain at higher-than-normal levels and will not return to normal flow before this next rain storm.
Precautionary/preparedness actions: “A flood watch means there is a potential for additional flooding based on current forecasts. You should monitor later forecasts and be alert for flood warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop. Please make all the necessary preparations today. If you experienced flooding with the last event, the course of least regret would be to prepare for it again. Because of the recent heavy rain the likelihood exists for this upcoming event to affect even more waterways and cause possibly higher crests.”
