Temperatures will begin to soar well into the triple digits in local deserts Sunday, according to the National Weather Service.
Forecasters say the heat will spread through most inland areas Monday and Tuesday, with more moderate temperatures in coastal and valley areas.
Not only will daytime temperatures be very hot, but overnight low temperatures will be elevated, especially in the low deserts, according to the NWS. Widespread moderate to high heat risk is expected.
San Diego River Gorge, Cedar Creek Falls, Three Sisters Falls and Eagle Peak trails will be closed starting Monday due to excessive heat.
The heat wave likely will run its course by the end of next week.
