Discussion
Another storm system will impact the region today and it will generate strong winds, periods of rain and possibly a strong thunderstorm or two. Rainfall amounts are likely to end up in the 1-3 inch range from this system with isolated higher amounts and - given the already pretty well saturated grounds - flash flood watches have been issued for much of the region. Winds will become quite strong from an E-SE direction as the low pressure system approaches and potentially can gust into the 40-50 mph range. With the expected long time period of an onshore flow during this storm, coastal flooding is a serious concern. The coastal flooding threat is not only for the Delmarva's Atlantic Ocean coastline, but also with respect to the Chesapeake Bay and tidal Potomac; especially, during tonight's high tide. It remains quite unsettled on Saturday with lots of clouds remaining and a continuing shower threat. The weather should settle down some for Sunday although a shower cannot be completely ruled out and Monday should turn out to be a dry and cool day.
