Seasonal Weather Highlights

October 7: Strong thunderstorms with heavy downpours drop up to 2 inches of rain over southwestern New Mexico during the afternoon. Flooding reported around Lordsburg, Animas, and Red Rock Canyon.

October 18: Severe thunderstorms rip southern Dona Ana County, New Mexico, and El Paso County, Texas during the late morning. Hail over an inch in diameter falls around Santa Teresa and west El Paso, damaging motor vehicles and destroying crops. Minor flooding and wind damage also reported.


October 23: Another round of strong to
severe thunderstorms strike southern New
Mexico during the late afternoon and evening.
One-inch diameter hail falls at Caballo in     
Sierra County.  
As expected, the weather started out very active across southern New Mexico and western Texas due to El Nino conditions over the eastern Pacific Ocean. Strong to severe thunderstorms with hail and high winds struck the region in October with colder more snowy weather developing from late November through December. However warm, dry, and occasionally windy weather returned in January. A slow moving low pressure system produced much-need widespread rains in late February. The first half of  March was warm and dry again before a series of low pressure systems brought windy, cooler and wetter weather across the Borderland.   

October 26. Thunderstorms produce one-inch
diameter hail at Orogrande in Otero County,
New Mexico with 3-inch deep hail
accumulations.

October 27. Showers and thunderstorms
push across southern Dona Ana and El Paso
counties during the late afternoon with
extensive street flooding across the city of
El Paso. These storms also produce half-inch
to three-quarter inch diameter hail.

November 26. Early winter storm brings heavy
snows to southern Sacramento Mountains.
Eleven inches of snow fall at Mayhill with six
inches falling around Cloudcroft.

December 4. Four inches of snow fall at
Cloudcroft.
