    The National Weather Service has issued a flood watch in advance of the next storm system that could bring a lot of rain to the Washington region.

    The flood watch will be in effect for most of the region for heavy rain beginning Wednesday night and continuing into most of Thursday, according to NBC Washington meteorologist Tom Kierein.

    A large area of low pressure moving through the mid-Atlantic states will draw copious amounts of moisture from the Gulf of Mexico and produce up to 3 inches of rain for much of the region.

    This will likely cause creeks and streams to come out of their banks on Thursday in addition to high water in low areas by Thursday afternoon.

    The rain could start after sunset Wednesday night. It will initially fall as light rain before dawn Thursday, and then become heavy at times during the day on Thursday.

    This storm is similar to the one that hit our area on Sunday, but actually has more moisture to it, Kierein said.

    The storm though should be gone Thursday night and dry weather is on tap for Friday and the weekend.

    However, during the weekend the runoff from all of that rain will swell area rivers, including the Potomac, to high levels over the weekend.
