* WHAT...High temperatures in the low to mid 90s across the interior and 80s along the coastline. * WHERE...The Bay Area and Central Coast. * WHEN...Until 8 PM PDT Friday. * IMPACTS...This level of heat affects most individuals sensitive to heat, especially those without effective cooling and/or adequate hydration. Impacts possible in some health systems and in heat-sensitive industries. Hot conditions can cause heat illnesses. * ADDITIONAL DETAILS...Much above normal temperatures in the upper 80s to mid 90s are expected through the remainder of the week across the Bay Area and Central Coast. Portions of the interior Central Coast may reach the upper 90s starting mid to late week. Overnight lows in the upper 50s to low 60s will offer some relief to the lower elevations but will offer minimal relief within the higher elevations. Conditions will be much above normal along the coast this week but coastal residents may experience more relief overnight than those across the interior. The risk of heat related illnesses will increase with each additional day of heating from this event.

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.
