Doppler weather radar for Washington, D.C., Maryland, and Virginia is broken

That radar, a WSR-88D model, is the most powerful one tasked with scanning the skies in northern Virginia, central Maryland, the eastern panhandle of West Virginia, and the District. It’s part of a network of 159 such Doppler radars nationwide maintained by the National Weather Service. Each radar emits high frequency pulses of energy, a portion of which bounce off precipitation targets and offer valuable information from inside a storm.

While the radar is down, forecasters will rely on airport radars and Weather Service radars at adjacent offices in State College, Pa., Pittsburgh, Mount Holly, N.J., Wakefield, Va., Dover, Blacksburg, Va., and Charleston.

This network of radars can stitch together a reasonable representation of storm surveys.

The region has some of the best radar coverage in the country thanks to four smaller, less powerful “terminal” radars at the three major airports, Dulles, Reagan National and BWI Marshall, as well as

SAIC wins major role in Air Force multi-domain command and control system — Washington Technology

SAIC wins major role in Air Force multi-domain command and control system

Alongside a new round of awards to 15 companies the Air Force announced Wednesday, the service has made a second $878.2 million award to one company.

Both awards are related to the development of the Joint All Domain Command and Control system known as JADC2.

Science Applications International Corp. was tapped for the single award through the OASIS vehicle. SAIC will develop solutions to be delivered through JADC2.

The company doesn’t have clearance from its customer yet to comment on the award, which will stretch out over five years if all options are exercised.

JADC2 is the Air Force’s effort to create a system that can gather information from any sensor anywhere and across any domain and disseminate anywhere it is needed regardless of platform.

University of Washington to test smartphone technology that tells you if you were exposed to the coronavirus; here’s how it works

This fall, the University of Washington plans to test smartphone technology that tells users if they may have been exposed to the virus that causes COVID-19.

Depending on how that pilot program goes, it could become available throughout Washington, said state Department of Health (DOH) spokesperson Cory Portner.

The Exposure Notifications System for iPhones and Android phones uses Bluetooth technology developed by Apple and Google to detect proximity to other phones. If someone who has enabled these notifications tests positive, they can anonymously and confidentially notify other users who have been within 6 feet of them.

“If you opt in to use the app and receive notification that you’ve been potentially exposed, the message will help you connect with public health to get recommendations on next steps,” DOH spokesperson Jamie Nixon said.

The design is aimed at preserving privacy by not collecting location data or sharing users’ identities, which might

► Friends join Sara Ali Khan for a weekend of partying

After spending her birthday month in a pool house, Sara Ali Khan seems to be in no mood to return. She has invited her friends over to the beach destination for a staycation. Sharing a pic of herself floating around in the pool, Sara quipped, “Gulab in Gulabi on Gulabo”. Despite being surrounded by friends, she chose to stick to reading historical non-fiction The Square and the Tower, even with heart-shaped glares on. Must be quite a page-turner, no?
