(Updated at 4:20 p.m.) Enjoy the dry weather while it lasts — Saturday is set to be exceptionally wet and windy.
Tropical Storm Ophelia is brewing off the southeast U.S. and is set to make its way up the coast and right over the D.C. area. It will bring with it heavy rain and strong winds.
The rain is expected to start late tonight but the storm will be at its peak Saturday afternoon and evening.
Here in Arlington, flooding along the coastline is expected Saturday, and local streams may also top their banks due to several inches of rain.
“Widespread rainfall amounts of 2 to 4 inches are expected, with localized amounts up to 5 inches possible,” the National Weather Service said in an advisory today. “This may result in isolated instances of flooding, especially for low lying and flood prone areas. The heaviest rain is most likely to occur Saturday into Saturday night.”
Those planning to attend outdoor events this weekend should keep an eye on the weather and monitor for possible cancellations.
The wind, meanwhile, could cause some power outage.
