An area of low pressure in the Gulf of California is going to streamline moisture into the Four Corners this week. A SLIGHT threat for heavy rainfall and flooding has been issued for the Four Corners region through Friday morning as this increased moisture more rain on areas already dealing with excess water from storms the last few days.

Rainfall totals could exceed several inches. Do not drive through flooded waters. Be on higher lookout for mudslides and debris flows from recent burn scars.

The Storm Prediction Center (SPC) has added some Marginal risks for severe storms over the Northern 4 Corners into this weekend.

Below is the latest on the timing of these showers and storms.
