Noon Monday - Hurricane Sally Update

Noon Update: Sally Has Strengthened into a Hurricane
Sustained Winds are now 90 mph. Pressure 986 millibars

Hurricane Warning Issued for the Entire Alabama Coast. Still looks like landfall will occur along the coast of Mississippi or near the MS-AL border.
I still believe the storm will reach sustained winds of 100 m.p.h. before landfall. Sally is reorganizing today and the latest data indicates pressures are falling -- down to 991 mb as of noon, the pressure has dropped rapidly to 986mb.

Major Storm Surge
This does not include waves or astronomical tides. It is possible the surge will be higher than forecast along the Mississippi coast -- a very dangerous situation.

Major Flooding Likely!
The peach color from the City of New Orleans to just off the coast of Mississippi is a forecast of 20 inches of rain. Major flooding will occur in eastern Louisiana and southern Mississippi.

Safety Recommendations With COVID Factored In:
  • Make a hotel/motel reservation well inland. There is no point to getting on the road and finding everything already sold out. Be sure and cancel if you do not need the room. In this case, I would go west (e.g., Lake Charles, Beaumont) to stay away from both winds and flooding. 
  • Make provisions for infirm friends/relatives well in advance. 
  • Get prescriptions filled before you evacuate. 
  • Put an app like AccuWeather's on your smartphone. It will keep track of your location and automatically provide the latest emergency warnings. 
  • Your "Go-Kit" should include at least two masks per person, soap, hand sanitizers, disinfectant wipes and, if available, disinfectant spray. 
  • Fill your car with fuel. I still recommend a road atlas or map in addition to whatever navigation system you might have. 
  • Power failures are likely. If you have a generator, fill it with fuel. If you wish to purchase a portable generator, do not put it in the garage, indoors, or anywhere near an air intake. Carbon monoxide is a danger. Nearly half of the fatalities from Hurricane Laura were from carbon monoxide after the storm. 
  • Consider taking your passport or putting it in your safe deposit box. If the worst happens, you'll need it to prove identity for disaster documents. It will be difficult to recover in a ruined home.
  • Take at least two large bottles of water for each family member along with protein bars or other easy-to-carry food. 
  • If you decide to stay home, make sure you have a working fire extinguisher, non-electric can opener, and a first aid kit. 
As always, I promise there will be no hyping of the storms.

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,
