The watch area includes Prince William, Fairfax and Arlington counties, as well as communities in and around Fairfax, Falls Church, Manassas, Alexandria, Leesburg, Ashburn and Sterling.

Wind gusts of 40 to 60 miles per hour are expected with the strongest storms.

Showers and storms will continue to increase in coverage and move through the rest of central NY between 4 pm and 9 pm.

Flash flooding is also possible throughout New York, New Jersey and CT as part of this storm.

As a result, atmospheric conditions have become unstable, and deteriorating weather conditions are expected to continue throughout the weekend. Plan to take shelter if/when NWS Sterling issues weather warnings. The day should be mostly sunny with a high near 83, the weather service says.
