Hydrologic Outlook

ESFABQ

* IMPACTS...River, creek, washes and arroyos may reach out of banks. Rock, mud and debris may flow into roadways and flash flooding can not be ruled out, especially in urban areas.

* CONFIDENCE...High confidence in widespread rainfall, with low confidence in river and flash flooding.

* WHAT...A strong Pacific storm system will interact with a atmospheric river streaming into the Desert Southwest and Four Corners region, producing widespread rain which will focus in the mountains.

* WHERE...Four Corners and surrounding region, including Aztec, Bloomfield, Farmington and Shiprock.

* WHEN...Sunday into Monday.

* ADDITIONAL DETAILS...River basins are already saturated from last week's rainfall and flooding, making additional runoff more efficient and can more easily cause flooding problems. The greatest precipitation amounts are forecast in the San Juan Mountains of Colorado, which will create high flows in the Animas and La Plata Rivers. These rivers feed the San Juan River, which saw record flooding last week.

Continue to monitor forecasts for the updates as this situation unfolds.
