Heat advisory issued for parts of the Bay Area starting Tuesday with temps near 100 degrees forecast

Part of the Bay Area will have a heat advisory in effect this week as a high-pressure system moves into the region from the Pacific. 

The National Weather Service said the inland parts of the North Bay and East Bay will see a significant warm-up starting Tuesday. The advisory will go into effect Tuesday at 8 a.m. and be over at midnight Thursday. 

Daytime highs are expected to be in the 90s and approach 100 degrees. The late evening and overnight temps will provide a break in the heat; the NWS expects temps to drop to between 60 and 70 degrees.

The South Bay will also have a heat advisory, but it won't be in effect until Wednesday 8 a.m., according to the NWS. It will end by Thursday night. 

Similar temps are expected in the South Bay. However, further inland there could be temps of 100 to 103 degrees, the NWS said. Nights will see temperatures drop to the 60s. 

The coastal regions are not expected to see high temperatures. The NWS expects temps in the upper 60s to mid-70s.

Residents are advised to take precautions as the hot temperatures could cause heat illness.
