The heat wave will subside some on Thursday, which will still be a warm day, with highs that might be in the 90s in the East Bay.

The weather service’s excessive heat watch does not include the coastlines of Sonoma, Marin and San Mateo counties and interior portions of Monterey and San Benito counties.

The hot weather also coincides with the Amgen Tour of California bike race that stretches between San Jose to Mount Diablo and begins on Tuesday. Race director Jim Burrell told KCBS that this year they will have a “mobile water fountain” in place.
