(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.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

If travel is required, allow extra time as some roads may be closed. Do not drive around barricades or through water of unknown depth. Take the necessary actions to protect flood-prone property.

While areas to the east are expected to see more significant impacts, local chapters of the American Red Cross said this morning that they’re gearing up for a disaster response.

More, below, via a press release.

As national preparedness month continues, the Red Cross of the National Capital & Greater Chesapeake region is making initial preparations to respond to potentially tropical storm-force wind and rain this weekend. Preparedness experts with the organization are also urging everyone to take action for this weekend’s severe weather and the worsening climate disasters in the DMV and on the Delmarva Peninsula—areas where the Red Cross has seen an increase in flood-related emergency responses in recent years.

According to NOAA National Centers for Environmental Information, in Maryland, the frequency of billion-dollar, weather-related disasters averaged more than five per year between 2018 and 2022— a 90%  increase when compared with an average of less than three per year between 2008 and 2012.

Severe weather like this is part of a worsening national trend in which the American Red Cross has responded to nearly twice as many large disasters across the country as it did a decade ago.

With more climate-driven disasters upending lives and devastating communities, the Red Cross is racing to adapt its services and grow its disaster response capacity locally and across the country, while also funding new international programs on climate response and preparedness; as well as minimizing its own environmental footprint.

“Everyone should take a forecast for severe weather seriously—especially because we are in a climate crisis in the DMV, the U.S. and across the globe,” said Dale Kunce, CEO for the Red Cross of the National Capital & Greater Chesapeake Region. “Today is the day to get your emergency plans in place.”
