The National Weather Service said above-normal temperatures were expected Monday through the weekend.
“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 well 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,” National Weather forecasters said.
Warm overnight temperatures are also expected and could lead to heat risk, according to the weather service.
A slight cooling trend will begin late in the weekend, with temperatures falling to between 77 and 86 degrees on Sunday.
The NWS said the level of Monday’s heat affects most individuals sensitive to heat, especially those without effective cooling and/or adequate hydration. The hot weather could also lead to possible impacts in some health systems and heat-sensitive industries.
The National Weather Service advised limiting outdoor activity and monitoring for heat-related illness. Take frequent breaks and stay hydrated. If caught outside, seek shade.
There is a moderate risk of heatstroke from Sunday through Wednesday and a minor risk all week, through Saturday, according to the Weather Servic
Forecasters advised everyone to check in on people who are sensitive to heat.
