— A MODERATE<\/strong> flood threat has been issued for the flood threat has been issued for the Bull Draw, Plateau, Burro and 416 burn scar areas <\/em><\/p>\n — A LOW<\/strong> flood threat has been issued for the Southwest Slope, San Juan Mountains, Central Mountains, Grand Valley, Northern Mountains and Northwest Slope<\/em><\/p>\n The main axis of subtropical moisture associated with the remnants of Hurricane Rosa will make its way into southwest Colorado and move NNE throughout the day. This will bring widespread<\/span> showers and thunderstorms to western Colorado as well as over the higher terrains through tomorrow morning. While the threat for rainfall is widespread<\/span> today, the largest totals will be confined to higher terrains over the Grand Valley, Central Mountains, Southwest Slope and San Juan Mountains. The snow line is expected to be somewhere between 12,000 and 13,000 feet, so only the highest peaks will have a dusting of snow by tomorrow morning. As anticipated, Precipitable Water<\/span> (PW<\/span>) has increased drastically over Grand Junction, and PW<\/span> was measured at 0.98 inches in the 12Z sounding. This surpasses the daily record, but the October record of 1.05 inches remains (for now).<\/p>\n This morning, the first wave of showers has made its way over the Southwest Slope and San Juan Mountains associated with the shortwave<\/span> marked in the water vapor imagery below. This feature and associated stratiform rain will continue to move to the NNE throughout the morning into this evening. Expecting showers to become lighter and less widespread<\/span> as they move into the Northern Mountains and Northwest Slope. None the less, 24-hour totals just under 1 inch will be possible over the Northern Mountains. A second wave of showers is expected to move into the southwest corner of the state this afternoon associated with the second shortwave<\/span> marked in the water vapor imagery below. Widespread<\/span> stratiform rainfall is forecast with some embedded convection<\/span> (limited instability) through early tomorrow morning. Some light, isolated<\/span> showers will likely continue over the Central and San Juan Mountains into Wednesday. Normally, stratiform rain and steering winds around 20 knots would keep the flood threat low. However, the multiple rounds of storms in a high moisture environment and convection<\/span> embedded in the showers will warrant flood threat today. Recent burn scars will be especially susceptible to flash flooding<\/span>, mud flows and debris slides. A Low flood threat has been issued for western Colorado with a Moderate Flood threat for the Plateau, Bull Draw, Burro and 416 burn scars.<\/p>\n
