DISCUSSION
LOW FIRE DANGER DUE TO HEAVY RAIN THIS WEEK. LIGHT SSW WINDS THIS
AFTERNOON, 5 TO 10 MPH LEADING TO FAIR VENTILATION. SCATTERED
SHOWERS AND THUNDERSTORMS EXPECTED AGAIN THIS EVENING ACROSS
LINCOLN NF. LOCALIZED FLASH FLOODING IS THE MAIN THREAT,
ESPECIALLY OVER BURN SCARS, MOUNTAIN CANYONS, AND OTHER FLOOD-
SENSITIVE LOCATIONS. RAIN CHANCES WILL SHIFT EASTWARD OVER THE
WEEKEND, WITH CHANCES DECREASING ACROSS GILA NF AND WESTERN NM.
RISK OF FLOODING WILL REMAIN FOR LINCOLN NF ON SATURDAY. THIS
WEEKEND SHOWS A DOWNTREND IN STORM COVERAGE, WITH SUNDAY BEING THE
DRIEST DAY OF THE FORECAST. ABOVE NORMAL PRECIPITATION LOOKS TO
RESUME AGAIN NEXT WEEK, ALLOWING ERCS TO PLUMMET AND KEEPING FIRE
DANGER VERY LOW.
