Flash Flood Watch

Flash Flood Watch went into effect from 3:43 AM today, until 6 AM on 6/19/2019. Be prepared to take action in the event that flooding develops.

The Flash Flood Watch is now in effect for

* Northeast Maryland, Delaware, central and southern New Jersey,
and southeast Pennsylvania.

* Through late tonight

* Another round of showers and thunderstorms is expected today
into this evening. The strongest storms will be capable of
producing torrential downpours, and the storms may have a
tendency to move over the same areas. Rainfall totals of 1 to 3
inches may occur in a short amount of time. This could lead to
localized flash flooding.

* The risk of flash flooding is highest with storms that produce
excessive rainfall rates for an extended period of time.
Flooding is most likely in more urbanized areas, in areas of
poor drainage, and in locations that have received heavy
rainfall the past few days. Rapid rises on small creeks and
streams are possible.
