Heat, fire risk and high tides are converging on the Bay Area this weekend, according to the National Weather Service. "Saturday and Sunday will be the hottest days of this heat advisory period," said weather service meteorologist Anamaria Navarrete. The most concerning fire conditions will happen during the afternoons and evenings, as sea breezes increase after sweltering hot days, according to the weather service. People who live near the shore or who are heading to those areas to beat the heat should be wary of the marine forecast, which is calling for high tides and localized flooding in some areas. "I want to emphasize the minor coastal flooding that areas along the bay shore and the North Bay will experience, and along the Central Coast," Navarrete said.
