Excessive heat watch issued for Antelope Valley

An excessive heat watch has been issued for Antelope Valley as triple-digit above-average temperatures are expected on Tuesday, the National Weather Service said.

Temperatures are expected to reach 107 degrees in Lancaster and 106 in Palmdale, about 10 degrees warmer than average for this time of year, said Oxnard Weather Service meteorologist Robbie Munroe.

Temperatures will potentially be higher in some areas of Antelope Valley.

“We are already seeing very hot conditions there and that will only settle in tomorrow partly due to some downhill, compressional heating from the Tehachapi Mountains in combination with a strong ridge aloft,” said said Munroe. “Tomorrow we are looking at widespread highs of around 104-108.”

The excessive heat watch will be in effect Tuesday from 10 a.m. to 8 p.m., Munroe said. The weather service could decide to turn the advisory into an excessive heat warning by Monday afternoon, Munroe added.

Residents are encouraged to drink plenty of fluids and to stay in air-conditioned rooms and out of the sun as much as possible. They are also asking residents to verify relatives and neighbors.

“Young children and pets should never be left unattended in vehicles. This is especially true in warm or hot weather when car interiors can reach deadly temperatures within minutes,” the National Weather Service said in an alert released Monday.

Monday and Tuesday nights in the Antelope Valley will see little respite with temperatures lower into the 70s to 80s.

“We could have a nice little break in temperatures as we head into the end of the week,” Munroe said. “It’s still quite warm for this time of year, but much cooler than we expected for Tuesday.”

Temperatures are expected to range from 100 to 104 degrees on Wednesday, about three degrees cooler than Tuesday. The weather is expected to stay in the triple digits for the rest of the week and could dip into the 90s over the weekend, Munroe said.

There are no other excessive heat watches in effect in southwestern California, according to Munroe. However, the inland coastal valleys should expect triple digit weather. The western San Fernando Valley and much of the Santa Clarita Valley will experience temperatures up to 105 degrees.

These high temperatures will spread to interior portions of Santa Barbara and San Luis Obispo counties, Munroe said.

Cooler temperatures in the 70s are expected towards the coast, and downtown Los Angeles should expect a high in the 80s.
