Temperature & Precipitation Outlook

Look Before You Lock!

Some storms in northern and central New Mexico will be capable of producing locally heavy rainfall and flash flooding this evening.

Moderate to extreme heat risk will return to parts of northern and central New Mexico on Wednesday.

Some monsoon thunderstorms will be capable of producing locally heavy rainfall and flash flooding each afternoon and evening over the next seven days. High temperatures will also reach into the 100s in many lower elevation locations each day.

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.
