Heat causing hot, dry & dangerous conditions

Posted: Updated:

San Diego is in today for a second straight day of triple-digit heat, strong winds and very low humidity, according to the National Weather Service.

A red flag warning signaling a high risk of wildfire was issued by the NWS Tuesday morning and was scheduled to expire at 9 p.m. Thursday.

Today's forecast calls for winds of between 15 and 25 mph through mountain passes and gusts of up to 35 mph in wind-prone areas.

Forecasters said they expect the winds to be strongest in the morning, diminishing slightly in the afternoon and evening. The humidity level will fall below 10 percent, according to NWS forecasters.

By Thursday afternoon, the winds will be lighter but low, single-digit humidities will persist, according to the Weather Service.

Marginally cooler days are expected Thursday and Friday before the heat wave begins to break Saturday, the agency reported.

NWS forecasters said highs will be 10 to 20 degrees above average for the season throughout the heat wave.   

The warmest parts of the county have been the inland valleys and foothills, such as Ramona, where the high Tuesday was 104 degrees.
