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
