Areal Flood Advisory, Flash Flood Watch:
Issued at: 9:45 am MDT on September 22, 2014, expires at: 10:00 PM MDT on September 22, 2014
- The National Weather Service in Albuquerque has issued an
- Arroyo and Small Stream Flood Advisory for... southeastern Lincoln County in central New Mexico western Chaves County in southeast New Mexico
- until 1145 am MDT
- at 941 am MDT National Weather Service Doppler radar indicated areas of moderate to heavy rain expanding in coverage west of the Pecos River valley to the east slopes of the northern Sacramento Mountains. Hourly rainfall rates up to one third of an inch are generally expected with isolated heavier amounts favoring areas between Roswell and Picacho north to Arabela. Even moderate amounts of additional of rain on top of the saturated conditions will result in rapid runoff with high flows continuing in arroyos... draws...and small creeks and streams that feed toward the Pecos River.
- Strong flows and high water levels are expected in arroyos...small streams and over low water crossings. Rapid runoff can also be expected immediately over and downstream from wildfire burn scars. Precautionary/preparedness actions... Both localized and distant heavy rainfall will create dangerous flows in arroyos and over low water crossings. Do not attempt to drive through these waters. Water in arroyos may travel many miles and take hours to reach your location from upstream rain areas. The heavy rainfall and slow movement of these storms may result in flooding of Road intersections and low-lying areas. Waters may begin to run in normally dry arroyos.

The Flash Flood Watch continues for
- a portion of north and central New Mexico...including the following areas...Central Highlands...Chaves County plains... Curry County...De Baca County...eastern Lincoln County... Guadalupe County...lower Rio Grande Valley...Quay County... Roosevelt County...San Francisco River Valley...south Central Highlands...south central mountains...southwest Chaves County... Southwest Mountains and upper Tularosa Valley.
- Through this evening
- an upper level low pressure trough over the eastern Great Basin early this morning will track through the central rockies later today. As it advances eastward...moist low level southeast through south winds and a continued tap of late season monsoon moisture will persist. The combination of these features will keep showers and thunderstorms active through this evening... and therefore the potential of heavy rainfall over the watch area.
- Locations which have received heavy rainfall recently will be most at risk of flash flooding. Other vulnerable locations include poor drainage areas...steep terrain and burn scars such as the Little Bear and Whitewater Baldy. Keep a watchful eye on small streams and arroyos...and avoid flooded low water crossings. Precautionary/preparedness actions... A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation. Monitor later forecasts and be prepared to take action should flash flood warnings be issued.
