Algodones Warnings, Watches and Advisories

Flood Watch issued September 21 at 1:02AM MDT until September 23 at 6:00PM MDT by NWS Albuquerque NM

* WHAT...Flash flooding caused by excessive rainfall is possible. * WHERE...Portions of central, east central, north central, northeast, southeast, and west central New Mexico, including the following areas, in central New Mexico, Central Highlands, Eastern Lincoln County, Estancia Valley, Lower Rio Grande Valley, Middle Rio Grande Valley including the Albuquerque Metro Area, San Agustin Plains and Adjacent Lowlands, Sandia and Manzano Mountains including Edgewood, South Central Highlands, South Central Mountains and Upper Tularosa Valley. In east central New Mexico, De Baca County and Guadalupe County. In north central New Mexico, East Slopes Sangre de Cristo Mountains, Espanola Valley, Glorieta Mesa Including Glorieta Pass, Jemez Mountains, Northwest Highlands, Santa Fe Metro Area and Southern Sangre de Cristo Mountains. In northeast New Mexico, Eastern San Miguel County, Far Northeast Highlands, Harding County and Northeast Highlands. In southeast New Mexico, Chaves County Plains and Southwest Chaves County. In west central New Mexico, Southwest Mountains, West Central Highlands and West Central Mountains. * WHEN...From Tuesday afternoon through Wednesday afternoon. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Creeks and streams may rise out of their banks. Flooding may occur in poor drainage and urban areas. Low-water crossings may be flooded. Storm drains and ditches may become clogged with debris. Extensive street flooding and flooding of creeks and rivers are possible. * ADDITIONAL DETAILS... - A dangerous surge of monsoon moisture will arrive Tuesday and Wednesday with widespread heavy rain. Scattered occurrences of flash flooding are likely, and there will probably be some main stem river and tributary flooding, as the most likely rain amount by Wednesday afternoon exceeds 2 inches in many locations along and east of the central mountain chain, and 1 inch in many locations westward to the continental divide. Stronger storms will produce torrential rainfall at rates over 2 inches per hour, and storms will train repeatedly in succession over some locations, with locally heavier rain amounts reaching 4 to 6 inches over portions of central and eastern New Mexico. Heavy rain will likely continue Wednesday night over eastern areas, then showers and storms with locally heavy rainfall are forecast to return along and east of the continental divide again on Thursday. - Rapid runoff and flash flooding will be most likely in complex terrain, below recent burn scars, low-lying areas, urban areas, normally dry arroyos, and near rivers and streams. As the event unfolds, locations with saturated ground will also become prone to rapid runoff and flash flooding from additional rounds of storms. - http://www.weather.gov/safety/flood

Flood Watch issued September 20 at 11:18PM MDT until September 23 at 7:00PM MDT by NWS El Paso Tx/Santa Teresa NM

* WHAT...Flooding caused by excessive rainfall is possible. * WHERE...Much of south-central New Mexico and Far West Texas, including El Paso, Las Cruces, and the Mesilla Valley. * WHEN...From Tuesday afternoon through Wednesday evening. * IMPACTS...Excessive runoff may result in flooding of arroyos, rivers, streams, and other low-lying and flood-prone locations. Flooding may occur in poor drainage and urban areas. Low-water crossings may be flooded, resulting in road closures. * ADDITIONAL DETAILS... - An early season back door cold front will interact with a late season plume of deep monsoonal moisture, bringing several rounds of thunderstorms with torrential downpours to the region Tuesday afternoon through Wednesday evening. Repeated thunderstorms may tend to focus in one or two areas, resulting in higher end precipitation totals. The most critical period with the heaviest rain potential will likely be Tuesday night into Wednesday morning. - A broad swath of moderate to locally heavy rainfall is likely to affect most of the Watch area between late Tuesday afternoon and Wednesday evening, with typical, scattered monsoon season flood impacts. However, there is increasing potential for a narrow band of repeated thunderstorms which will result in particularly heavy rainfall amounts, possibly exceeding 3 inches in a 6 to 12 hour period, resulting in higher-end impacts. Forecast models currently favor placing the focus for heaviest rainfall over the Mesilla Valley and El Paso. But forecasts this far out, especially when dealing with thunderstorms, are simply not accurate enough to precisely tell yet where exactly this area of heaviest rainfall will set up. It could just as easily shift west or east and avoid the more populated corridor. - http://www.weather.gov/ElPaso

When a severe thunderstorm warning is issued, the storm may produce damaging winds, large hail, dangerous lightning, and heavy rain. In some cases, heavy rainfall produced by a severe storm can also lead to flash flooding. Do not drive vehicles through flooded areas. The water depth or fast flowing water/mud/debris from a flash flood will make road conditions unsafe. Do not rely soley on data presented here or other third-party websites - always check your official national and local weather service agency website, socials, radio and/or TV stations for making critical decisions related to weather events.

Please carefully read each posted Warning and Alert as it relates to the area(s) being affected. We may provide a wider range of issued severe weather warnings for surrounding cities and counties, so some alerts may not directly impact this location. This is done to help with preparing for severe weather that may overlap or be heading towards Algodones.
