Another Too-Late Tornado Warning

By -
This has become far too common. Another obvious tornado warning situation where the National Weather Service in southwest Wisconsin waited too long to issue a tornado warning. Jeff Piotrowski, I, and a third meteorologist were tweeting about the threat but the NWS didn't issue a tornado warning until the storm was on the ground, lofting debris. Let's pick things up at 1:34pm (the time my tweet, below, appeared on the timeline).

The rotation continued to increase. I was shocked by the fact a tornado warning had not been issued. 

Again, it was shocking to me that a tornado warning wasn't out.
Finally, at 1:48, the NWS issued a tornado warning.

The problem is that the tornado had already been on the ground for at least two minutes. 
The bottom display of lofted debris showed a considerable area of debris at 1:46pm -- two minutes before the tornado warning was issued. The rotation display showed an obvious tornado signature. Using an experimental program, the tornado was estimated to be EF-2 intensity. 

I'm not aware of any injuries or significant damage from this tornado which, fortunately, occurred in a rural area. There were injuries with the unwarned tornado northeast of downtown Philadelphia July 29. I fear it is just a matter of time before needless fatalities occur as they did in Joplin.

This is yet another reason why our nation needs a National Disaster Review Board.

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,
