Warm temperatures will continue throughout the week and will exceed 100 degrees in desert communities, triggering an excessive heat warning that will remain in effect for affected areas through Thursday night.
Monday morning started with a dense fog advisory that lasted until 8 a.m. for coastal areas, the National Weather Service said. With the fog cleared, the county's only active weather advisory is that of the excessive heat in East County.
Dangerously hot conditions will continue to scorch desert areas with an excessive heat warning that will continue through 9 p.m. Thursday. Extreme heat will increase the potential for heat-related illnesses, according to NWS.
NBC 7 meteorologist Sheena Parveen says that with plenty of sun on Monday, residents should wear sunscreen that has an SPF of 30 or more.
Tuesday and Wednesday are expected to be the hottest days of the week, so remember to keep hydrated and wear clothes that will keep you cool.
