MENDOCINO Co., 8/16/22 — A red flag warning and heat advisory has been issued by the National Weather Service (NWS) in Eureka for portions of the interior North Coast on Wednesday, August 17, as high temperatures and erratic winds are expected, which in combination the current dry conditions could lead to increased wildfire risks. The red flag warning is currently in effect beginning at 11 a.m. Wednesday and lasting until 11 p.m. NWS has also issued a hazardous weather alert forecasting a high potential for thunderstorms on Wednesday evening in eastern Humboldt, Del Norte, and northeastern Mendocino County, which could increase risky fire conditions.
The heat advisory began this morning, and is effect until 8 p.m. Wednesday. Temperatures in interior Mendocino County as well as Lake County and southern Trinity County could reach up to 110 degrees, and residents should take caution to stay hydrated and protect against the heat. The temperature at the Ukiah airport reached a record breaking 108 degrees today, according to NWS, breaking the previous record of 106 degrees set in 1920.

Due to the high temperatures across the state, the California Independent System Operator, which maintains the statewide power grid, has issued a flex alert for Wednesday, in anticipation of additional power use and strain on the grid, and has asked customers to minimize power during peak hours between 4 p.m. and 9 p.m. You can read the full statement here. As of Tuesday evening, there were no anticipated planned power outages announced in the PG&E weather forecast, which provides information about possible electric shutoffs during the upcoming week.
The Mendocino County Air Quality District has also issued an alert warning that reduced air quality and smokey conditions may be ongoing through at least Friday — you can read more details about that in our earlier article.
