Even Alamosa got in on the action and recorded around a quarter of an inch for the 24-hour period. Along the valley edges, the Great Sand Dunes received between 0.4 and 0.5 inches due to storms favoring the southwest facing slopes with southeasterly flow driving the storm&rsquo;s direction. Several SNOTEL stations in the area recorded 0.4 inches for Sunday. Fortunately, rainfall was gradual enough and soils were dry enough that no flooding was reported as of this morning.<\/p>\n<p>As a reminder, it has been very dry and hot over the state the last couple of weeks, which has helped dry out vegetation.

Also shown optionally are vulnerable fire burn areas (post 2012), which are updated throughout the season to include new, vulnerable burn areas.
