Forecasters said they will probably let the heat advisory expire at 9 p.m. but they may extend it.

Forecasters said some hints of minor cooling are appearing, with west winds blowing near the Golden Gate and San Francisco International Airport.

West winds cooled by 60-degree ocean waters will cool the Bay Area, NWS forecaster Steve Anderson said. The strength of the winds determines how much of the inland Bay Area gets cooled, he said.
