Triple-digit weekend temps raise fire risk

San Francisco Bay Area residents face increased danger from wildfires and heat-related illnesses Friday and Saturday as the weather gets hot and windier, according to the National Weather Service.

Temperatures, especially in interior locations, will begin to rise Friday and soar to near 100 degrees, rising even more Saturday with some inland locations possibly reach 105.

Coastal temperatures will be lower, and weather officials expect residents to flock to the beaches to stay cool. Water temperatures will be in the 50s.

Conditions ripe for wildfires will arise Friday afternoon and last until Saturday afternoon for the East Bay hills and North Bay mountains. Weather officials said any fires that spark have the potential to spread.

Cooler temperatures are expected for Sunday and Monday.
