Heat expected to break Wednesday

Ramona experienced a high of 104 degrees on Monday, and dry and hot daytime temperatures will persist throughout most of San Diego County Tuesday, forecasters said.

Daytime highs Tuesday will be in the upper 90s to low 100s in the inland valleys, upper 100s in the lower deserts, upper 90s in the high deserts, upper 80s to low 90s at lower mountain elevations and in the 80s in coastal areas, according to the National Weather Service.

“Daytime humidities will be in the teens for inland areas, resulting in continued fire weather concerns,” according to an NWS advisory.

Tuesday is expected to mark the final day of a heat wave that began Sunday. According to the Weather Service, as high pressure over California and Baja shifts southward and weakens, cooler temperatures will prevail for the rest of the week and into early next week.

During this week’s heat wave, the county of San Diego Health and Human Services Agency encouraged residents without access to air conditioning to use one of the Cool Zone locations in the region. In Ramona, those are the library at 1275 Main St. and the community center at 434 Aqua Lane.

The purpose of the county-sponsored Cool Zone program is to offer free access to air conditioning for those whose homes do not have it or those who cannot afford the hefty power bills typically generated by air conditioner use.

Low-income, senior and disabled residents who have trouble traveling can request a free electric fan through the program. For more information, call 800-510-2020.
