GILROY, Calif. - The National Weather Service has issued red flag warnings and fire weather watches to alert fire departments of the possible onset of dry conditions and critical weather that could lead to increased fire activity.
The new red flag warning has been issued for the Diablo Range in Santa Clara County from 11 p.m. Wednesday through 5 p.m. Thursday.
Increasing northerly winds and drying conditions are forecast to return to the region late Wednesday and persist through Thursday afternoon in wake of a weak, dry frontal passage. Low humidity and gusty northerly winds will combine with dry fuels to produce critical fire weather conditions, especially in higher elevations of the North and East Bay Hills/Mountains.
WIND: Northeast winds of 15 to 30 MPH with gusts to 45 MPH, especially in elevations above 1500 ft.
HUMIDITY: Minimum daytime values between 10-20 percent with night time recovery values between 30-40 percent, especially in elevations above 1500 ft.
IMPACTS: Any fires that develop will likely spread rapidly. Outdoor burning is not recommended.
A RED FLAG WARNING means that critical fire weather conditions are either occurring now or will shortly. A combination of strong winds, low relative humidity, and warm temperatures can contribute to extreme fire behavior.
