Upgraded Middle Atlantic Tornado Risk

By -
The tornado risk in the Middle Atlantic states has been upgraded to 15% This includes Harrisburg, Baltimore, Washington, and Richmond. This is a substantial number! 


The damaging thunderstorm wind 30% probability area has been enlarged and now includes Pittsburgh.

I urge people in the affected areas to keep up on the weather as these storms develop and approach. 

As of 12:40 EDT, AccuWeather regional radar shows a strong line of thunderstorms that will continue to intensify and produce the damaging winds.  The tornado-bearing thunderstorms have not yet formed but will generally occur ahead of the line of thunderstorms. This means some areas may have two rounds of severe thunderstorms.
 

Airline travel will be disrupted this afternoon and evening throughout the region.

I will not be live-blogging these storms. There will be updates from AccuWeather here and

Hilary's Forecast Path Shifts West; Updated 9:20am PDT

The forecast path of the center of Hilary has shifted a bit to the west. This increases the threat to the Southland, especially in terms of flooding.  Rainfall Note the heavy rains are forecast for Los Angeles County. Serious flash flooding may result. Because the forecast path has shifted to the west, that increases the threat of serious flooding in Los Angeles County north into Yosemite and the southern Sierra. It lessens the threat in Utah and western Arizona. While the threat of widespread flooding in Utah and Arizona lessens, note that some thunderstorms with localized heavy rain show up on the map.  In Nevada, the more western path increases the risk of serious flooding around Mt Charleston and into the central part of the state.  Here is the updated  (9am PDT) flash flood risk map. Wind There are already about 40,000 people without power in California, mostly in the center of the state.  The maps above are the peak gusts forecasted with the storm. The highest winds, in general,
