Sixth Tornado Watch Issued

By -
The red outlines are tornado watches. Blue is a severe thunderstorm watch.


The latest watch is in effect until 4am and the risk of tornadoes is "high" and risk of violent tornadoes is  "moderate."
Nighttime tornadoes is the worst possible situation. Please turn on your NOAA Weather Radio and set the tone-alarm feature. If you do not have a weather radio,
  • Go to WeatherCall and subscribe to their service. Because they use the NWS's polygons, they will call you during the night is there is a genuine tornado threat and their system gives you a lower chance of a false alarm. I recommend them even if you have a weather radio as it is always a good idea to have more source for tornado warnings. 
  • Put a TV remote or a radio near your bed and flip it on immediately if you hear thunder during the night. 
  • If you live in an area with sirens, crack a window near your bed to improve your chances of hearing it.
The above two suggestions are not a substitute for having a weather radio but they improve your chances for tonight. 

I am not live-blogging these storms or doing any coverage because we are still having network issues at my home. I don't want you to depend on the blog when there is a chance I can't get something critical posted in a timely fashion.

Of course, AccuWeather updates its web site during the night.

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.
