Look Before You Lock!

Showers and thunderstorms are expected across much of the high terrain this afternoon before rolling off onto adjacent lower elevation areas. Storms will be capable of producing locally heavy rainfall, flash flooding, gusty winds and frequent lightning.

Moderate to major heat risk is expected for most areas today and Wednesday. A Heat Advisory is in effect for today for Farmington, Espanola, the middle and lower Rio Grande Valley, and the east central and southeast plains. Those without adequate cooling or hydration will be susceptible to heat illness.

High temperatures will be in jeopardy today as afternoon temperatures soar into the 90s and 100s. Areas likely to break temperature records include Clovis, Fort Sumner, Moriarty, Portales, Roswell, Santa Fe, and Tucumcari.

Never, never, never leave children, disabled or elderly adults, or pets in parked, unattended vehicles! Studies have shown that the temperature inside a parked vehicle can rapidly rise to dangerous levels for people and pets. Leaving the windows slightly open does not significantly decrease the heating rate. The effects can be more severe on children because their bodies have not developed the ability to efficiently regulate internal temperature.
