Red flag warning extended again


A “red flag’’ warning, signaling a high risk of wildfire, was extended through 8 p.m. today in the valleys and mountains of San Diego County.

The alert, which was issued first Wednesday morning, was to have expired Monday night, but the National Weather Service subsequently extended it as forecasts showed that dry air and warm temperatures are likely to linger in the region.

The warning indicates that heat, high winds and low humidity will create the potential for “explosive fire growth.’’
