What to do

Do not drive through flooded roads. The National Weather Service says most flood deaths occur in vehicles. Turn around and find another route, and do not go around barricades.

Be extra careful tonight. Darkness makes it harder to see how deep or fast the water is. Stay off roads in low-lying areas, underpasses and near creeks if you can.

Stay alert even if it is not raining where you are. Arroyos, streams and rivers can rise within minutes from rain that fell farther away. If water rises near you, move to higher ground.

Just 6 inches of moving water can knock you down, and 1 foot can sweep a vehicle away.

Context

FEMA flood-insurance records show 130 claims in Otero County between 1983 and 2025, as of September 9, 2026. These counts include only insured properties, so they likely understate total flood impacts in the county.

This history shows that flooding has happened in the county before. It does not predict what will happen tonight.
