The good news first, the South Platte basin is hovering right around normal for this time of year, thanks to several large snow events that blanketed the Northern Front Range in March and April. However, the rest of Colorado is in much worse shape in terms of snowpack. Basins along the western slope have less than 70% compared to 1981-2010 averages, and severe to exceptional drought conditions are present across the Western Slope, as seen in the second map from the U.S. Drought Monitor.&nbsp;&nbsp;Drought is one of the many factors that can affect the severity of fire season, something important to remember after the extreme fire season in late 2020. A change in the weather pattern over the weekend is anticipated to bring some much-needed moisture across the state, and hopefully boosting the snowpack totals closer to normal.<\/p>\n<p><a href=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/05\/co_swepctnormal_update_20210501.png\"><img loading=\"lazy\" class=\"aligncenter wp-image-13485 size-large\" src=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/05\/co_swepctnormal_update_20210501-1024x791.png\" alt=\"\" width=\"910\" height=\"703\" srcset=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/05\/co_swepctnormal_update_20210501-1024x791.png 1024w, https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/05\/co_swepctnormal_update_20210501-300x232.png 300w, https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/05\/co_swepctnormal_update_20210501-768x593.png 768w, https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/05\/co_swepctnormal_update_20210501.png 1056w\" sizes=\"(max-width: 910px) 100vw, 910px\"\/><\/a><\/p>\n<p><a href=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/05\/current_co_trd_20210501.png\"><img loading=\"lazy\" class=\"aligncenter wp-image-13486 size-large\" src=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/05\/current_co_trd_20210501-1024x791.png\" alt=\"\" width=\"910\" height=\"703\" srcset=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/05\/current_co_trd_20210501-1024x791.png 1024w, https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/05\/current_co_trd_20210501-300x232.png 300w, https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/05\/current_co_trd_20210501-768x593.png 768w, https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/05\/current_co_trd_20210501.png 1056w\" sizes=\"(max-width: 910px) 100vw, 910px\"\/><\/a><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<h4 class=\"collapseomatic \" id=\"id6a1cad5fd6c56\" tabindex=\"0\" title=\"Click Here For Map Overview\">Click Here For Map Overview<\/h4><div id=\"target-id6a1cad5fd6c56\" class=\"collapseomatic_content \">\nThe map below shows radar-estimated, rainfall gage-adjusted Quantitative Precipitation Estimates (<span class=\"glossaryLink\"  aria-describedby=\"tt\"  data-cmtooltip=\"&lt;div class=glossaryItemTitle&gt;QPE&lt;\/div&gt;&lt;div class=glossaryItemBody&gt;&amp;lt;strong&amp;gt;Q&amp;lt;\/strong&amp;gt;uantitative &amp;lt;strong&amp;gt;P&amp;lt;\/strong&amp;gt;recipitation &amp;lt;strong&amp;gt;E&amp;lt;\/strong&amp;gt;stimate; an estimate of the amount of precipitation that has fallen at a particular location or across a region based on several different data sources, such as radar or satellite; QPE is often calculated using remotely-sensed data sources&lt;\/div&gt;\"  data-gt-translate-attributes='[{\"attribute\":\"data-cmtooltip\", \"format\":\"html\"}]'>QPE<\/span>) across Colorado.

The 24-hour, 48-hour and 72-hour total precipitation contain bias corrections that are not disaggregated into the hourly estimates, so there will likely be some differences.

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