SAN DIEGO (KGTV/CNS) - Some parts of San Diego County will likely see triple-digit temperatures Tuesday -- one day after heat records were broken in several communities.

As an Excessive Heat Warning remains in effect for most of the county, Tuesday’s forecast calls for temperatures in the mid- to high-90s and into 100 degrees in some areas.

The Excessive Heat Warning is scheduled to expire Thursday at 8 p.m. The warning does not impact San Diego’s coastal areas.

High temperatures are expected to range anywhere from 97 to 102 degrees in Escondido and El Cajon, and Vista was expected to see temperatures as high as 93 degrees.

Record temperatures Tuesday and Wednesday could be broken in San Diego, Vista, Chula Vista, Ramona, Alpine, Campo, Escondido, El Cajon and Borrego, according to the National Weather Service.

On Monday afternoon, the mercury topped out at 102 degrees in Ramona, tying the East County community's prior record for the date, set in 2006.

Other notable mercury marks included 101 in Alpine, 104 in Valley Center, 106 in Campo, 116 in Borrego Springs and 119 in Ocotillo Wells.

THE HEAT IS ON:

The extreme heat caused the U.S. Forest Service to announce an emergency closure of the Three Sisters and Cedar Creek Falls areas that remains in effect until Thursday due to health and safety concerns.

Temperatures near the immediate coast are expected to reach the high 80s, but not much higher.

The NWS issued a High Surf Advisory that began Monday at 8 a.m. and lasts through 9 p.m. Wednesday.

Strong rip currents and high surf could cause dangerous swimming conditions for inexperienced swimmers, the NWS said.

Surf levels of 5-9 feet will be possible, forecasters said.

The desert northeastern corner of San Diego County will continue to see high temperatures, with the mercury forecast to rise as high as 121 degrees today and 123 degrees Wednesday.

Authorities urge the public to avoid potential health hazards resulting from the extreme heat by drinking plenty of non-alcoholic fluids, seeking out shady and/or air-conditioned environments and checking up on relatives and neighbors to make sure they are handling the heat all right.

In addition, young children and pets should never be left unattended in vehicles during hot weather, when car interiors can reach lethal temperatures in a matter of minutes, officials warn.
