Look Before You Lock!

A greater coverage of showers and thunderstorms across the west central and north central mountains and adjacent western and northeast highlands Tuesday afternoon. Storms will be capable of producing locally heavy rainfall and resultant flash flooding.

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

Another very hot day expected across lower elevations on Tuesday with high temperatures in the mid 90s to mid 100s challenging record highs for many. Heat Advisory is in effect from 1 PM to 7 PM for the Northwest Plateau, parts of central NM and the east central and southeast plains.

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.
