NWS Los Angeles/Oxnard Weather Impacts for Sept. 30-Oct. 2

From the National Weather  Service:

This email is intended for critical weather partners in Los Angeles, Ventura, Santa Barbara, and San Luis Obispo Counties.

…Hot and Dry Weather Expected Sunday Through Tuesday…
…Heightened Fire Danger Due to Low Humidity, Offshore Winds, and Hot Conditions, Especially Monday and Tuesday…
  • Hot weather –  High temperatures on Sunday are predicted to be 95 to 105 inland with 80s to near 90 at the coasts. On Monday and Tuesday, offshore winds will increase over Ventura and Los Angeles Counties with high temperatures 100-107 in the valleys and well into the 90s at the coasts. Record high temperatures will be possible these two days. Nighttime lows should cool into the 60s and 70s. This will be a significant heat event for people without air conditioning closer to the ocean. 
  •  Fire danger –  The hot weather from Sunday through Tuesday will be accompanied by single digit humidities, very dry fuels, and 20 to 30 mph offshore wind gusts through and below passes and canyons of Ventura and Los Angeles Counties. Poor overnight humidity recoveries are also expected during the period.


A strong high pressure system will develop over California this weekend and persist into early next week. A large low pressure area well to the west of southern California will help generate light offshore winds, especially Monday and Tuesday that will boost temperatures potentially to record highs both for the valleys and coastal areas. Dry, hot, and breezy conditions will increase fire danger to elevated levels throughout the region. Expect the high pressure system to begin to shift east on Wednesday with temperatures lowering as winds turn more onshore.

There is high confidence of hot weather impacting the area and moderate confidence in the strength of the offshore winds for Monday and Tuesday.
