Heat advisory issued for SLO and Paso Robles

Both San Luis Obispo and Paso Robles will be under a heat advisory warning on Wednesday, with the National Weather Service forecasting temperatures as high as 92 degrees in SLO and 99 degrees in Paso Robles.

The advisory is expected to be in effect between 10 a.m. to 7 p.m.

During the advisory, the weather service warned there is a high risk for heat illness for sensitive populations like the “very young, the very old, those without air conditioning and those active outdoors.”

People were urged to drink plenty of fluids, stay in air-conditioned rooms, stay out of the sun and check up on relatives and neighbors.

Paso Robles will still see warmer temperatures, however, with a forecasted 95 degree high on Friday and 93 degrees on Saturday.
