Unseasonably warm temperatures will scorch San Diego County this week and trigger heat-related warnings and advisories for inland and desert communities, according to the National Weather Service.
Triple-digit temperatures are expected in desert areas Tuesday through Friday thanks to building high pressure throughout the county. By midweek, high temperatures could be 15-20 degrees above average in most areas, forecasters said.
The NWS issued a heat advisory that will be in effect from 10 a.m. Tuesday to 9 p.m. Friday in the western valleys.
An excessive heat watch will also take effect Tuesday morning and last until Friday evening in the county deserts.
NBC 7 meteorologist Sheena Parveen says it is important to stay hydrated, keep away from the sun to stay cool and to check up on elderly relatives and neighbors during these conditions.
She also reminds residents to refrain from walking their pets in the afternoon and do so early in the morning or later in the evening to avoid the scorching heat.

Also, young children and pets should be never be left unattended in a vehicle, with car interiors able to "reach lethal temperatures in a matter of minutes," the NWS said.
According to Parveen, if the temperature outside is 85 degrees, it takes just 10 minutes for the inside of a vehicle to reach 104 degrees, which can be deadly for children and pets left in cars.
Highs in the western valleys are expected to top out in the low-to mid-90s on Wednesday and Thursday, while the mercury in desert areas is projected to reach its peak at 108 on Thursday, forecasters said.
