9:40am Sunday: Hurricane Ida Update

By -

Ida is an upper Category 4 hurricane and still strengthening. It has a good chance of making it to Cat 5 intensity. 

Below is the radar at 9:34am. Catastrophic damage is likely between the two arrows as the still strengthening eye moves WNW then NW. Winds are 150 mph and the central pressure is down to 931 millibars. 


New Orlean is just above the center of the image. I have highlighted the area with sustained 100+ mph winds and have hatched the area with winds of of 140 mph or stronger. It continues to move to the northwest. As the National Hurricane Center puts it:

If you are in the path of Ida, you must shelter as you would for a tornado: Closet or bath in the center of the house. If you have a helmet of some type, wear it. 

Below is the map of the forecasted wind speeds.

There is a tornado watch outlined in red below.

Power is already out in southeast Louisiana and those numbers will rise.

Don't bother with a generator today. Once the storm has passed, follow the instructions to the letter.

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,
