Hydration is a critical piece to surviving the heat. Drink water, and
if possible, take water to those who are vulnerable.
Take extra precautions when outside. Wear lightweight and loose
fitting clothing. Try to limit strenuous activities to the early
morning or evening. Take action when you experience symptoms of heat
exhaustion and/or heat stroke.
Beat the heat and check the backseat! Do not leave young children or
pets in unattended vehicles. Car interiors will reach lethal
temperatures in a matter of minutes.
Cooling shelters may be available in your area. Check with your city
or county office of emergency management for locations and sign up
for local alerts via alertthebay.org.

* WHAT...Up to 1.7 ft of inundation above ground level is possible in low-lying areas near shorelines and tidal waterways. * WHERE...Bayshore locations along the San Francisco Bay, San Pablo Bay, and Monterey Bay. * WHEN...Until 2 AM PDT Thursday. * IMPACTS...Flooding of lots, parks, and roads with only isolated road closures expected. * ADDITIONAL DETAILS...At the San Francisco tidal gauge, high tide is expected to be 1.4 ft above normal (7.25 ft MLLW) at 8:00 PM Saturday 8/8, 1.7 ft above normal (7.54 ft MLLW) at 9:02 PM Sunday 8/9, 1.7 ft above normal (7.56 ft MLLW) at 10:01 PM Monday 8/10, 1.7 ft above normal (7.54 ft MLLW) at 10:57 PM Tuesday 8/11, and 1.4 ft above normal (7.24 ft MLLW) at 11:49 PM Wednesday 8/12. These predictions include both astronomical tides and roughly 4-8 inches of additional water mainly from a combination of thermal expansion and accumulated sea level rise since the tidal datum was established (1983- 2001). High tide varies up to 90 minutes earlier or later along the Pacific Coast and through the San Francisco Bay, respectively.
