Weather Alerts and Warnings for Las Cruces

Severe Future Possible

Flood Watch

Flood Watch issued September 17 at 2:25PM MDT until September 18 at 6:00AM MDT by NWS El Paso Tx/Santa Teresa NM
Sep 17, 2:25 PM Sep 18, 6:00 AM
WHAT: Flooding caused by excessive rainfall continues to be
possible.

WHERE: Portions of south central and southwest New Mexico,
including Sierra, Dona Ana, Luna, and eastern Grant Counties and
the Sacramento Mountains in northern Otero County.

WHEN: Through late tonight.

IMPACTS: Excessive runoff may result in flooding of rivers,
creeks, arroyos, low water crossings, and other low-lying and
flood-prone locations.

ADDITIONAL DETAILS:
- 24-hour rainfall observations shows a wide swath of 1-2" across
much of south-central New Mexico. High soil moisture will allow
runoff to occur quickly with any additional rounds of rain.
Thunderstorms are expected to track north across the Watch area
Thursday night into Friday morning, leading to localized flash
flooding. Additionally, risk of flooding continues for the
Sacramento Mountains, where storms initiating along a N/S
oriented ridge and parallel storm motions may lead to training
storms and prolonged heavy rain Thursday afternoon.
- This includes portions of the I-25 corridor through Hatch and
Truth-or-Consequences and the I-10 corridor through Las Cruces
and Deming.
