Heat advisory issued for Paso, Atascadero and SLO County’s interior valleys

A heat advisory has been issued in the North County due to high temperatures, according to the National Weather Service.

The advisory, which affects the cities of Paso Robles and Atascadero, as well as San Luis Obispo County’s interior valleys, went into effect at 10 a.m. Monday and will last until 9 p.m. Tuesday, the agency said.

The National Weather Service said it’s issuing the advisory because temperatures could be hot enough to cause heat-related illnesses.

The agency said it expects temperatures to reach between 94 and 104 degrees during the day. At night, temperatures are forecast to range from the mid 50s to the mid 60s, and will be warmest on the Carrizo Plain.

According to PG&E meteorologist John Lindsey, the Paso Robles Municipal Airport could reach a high temperature of 102 degrees on Monday, which comes close to the June 10 record of 105 degrees that was set in 1991.

The people most vulnerable to heat-related illness include those involved in outside activities, young children, the elderly and those with no air conditioning, the agency said.

The National Weather Service urged everyone to drink plenty of fluids, stay out of the sun, stay in an air-conditioned room and check on relatives and neighbors.

The agency also cautioned people not to leave children and pets alone in a hot car.

“Car interiors can reach lethal temperatures in a matter of minutes,” the agency said.

In the past week, temperatures have reached scorching levels in the North County. Paso Robles recorded its first triple-digit temperatures of the season on June 4, and hot and breezy weather helped spark a rash of fires that broke out from Santa Margarita to Lake Nacimiento over the weekend.

For Monday and Tuesday, PG&E’s fire index ratings are at high levels along the coast and coastal valleys and at very high levels for all inland valleys, Lindsey said.

Those ratings will lower to medium levels along the coast and coastal valleys on Wednesday, but will remain very high in the inland valleys.
