Major storm to bring heavy rain, high winds and serious tidal flooding to D.C. area Friday.

Some of the worst coastal flooding in recent decades is predicted along the Chesapeake Bay and in the Tidal Potomac.

* Flood watch for immediate D.C. area Friday | Coastal flood warning Thursday night to Saturday morning for Potomac River and Chesapeake Bay | Wind advisory for Anne Arundel County Friday | High wind warning for St. Mary’s and Calvert counties Friday *

A powerful storm system, which originated from the record-setting rain event in California and spawned tornadoes in the South, will bring multiple types of hazardous weather to the Washington region into Saturday.

Waves of rain, some heavy, will pass through the entire region Friday, which could cause pockets of flooding near streams and areas of poor drainage. Generally, 1 to 2 inches of rain should fall, with a few areas seeing up to twice that amount.

Winds, meanwhile, will gust to at least 30 mph in most areas — being strongest from midmorning into the afternoon. Along the western shores of the Chesapeake Bay, the gusts could top 50 mph, prompting wind advisories and high-wind warnings. The combination of the heavy rain and high winds is likely to cause scattered power outages.

But perhaps the most notable hazard will be the high water along the shores of the Chesapeake Bay and in the Tidal Potomac River, which could be 2 to 3 feet above normal, flooding unprotected areas.

“One of the biggest tidal flood events of the past 10-20 years (possibly since Hurricane Isabel at some locales), is expected Friday & Saturday,” the National Weather Service tweeted.
