Most of the rainfall occurred in the form of thunderstorms, focused over the climatologically favored Southeast Mountains, Raton Ridge and San Juan Mountains. Storms made the most of the marginal moisture and a few produced rainfall rates up to about 1.2 inches per hour over Las Animas County and up to 0.7 inches per hour over Conejos County. In Las Animas County, the heavy rainfall fell in close proximity to a few USGS gages and a quick streamflow spike from less than 1 c.f.s. to 60 c.f.s. was noted on the Van Bremer arroyo (see below).<\/p>\n<p><a href=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2017\/09\/van_bremer_arroyo_spike.png\"><img loading=\"lazy\" class=\"aligncenter size-full wp-image-6208\" src=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2017\/09\/van_bremer_arroyo_spike.png\" alt=\"\" width=\"576\" height=\"384\"\/><\/a><\/p>\n<p>The disturbance also knocked down the afternoon high temperatures closer to seasonal normal west of the <span class=\"glossaryLink\" aria-describedby=\"tt\" data-cmtooltip=\"&lt;div class=glossaryItemTitle&gt;Continental Divide&lt;\/div&gt;&lt;div class=glossaryItemBody&gt;&amp;lt;!-- wp:paragraph {&amp;quot;textColor&amp;quot;:&amp;quot;white&amp;quot;} --&amp;gt;\n&amp;lt;p class=&amp;quot;has-white-color has-text-color&amp;quot;&amp;gt;the dividing line that separates the watersheds of the western and eastern United States; rivers west of the divide empty into the Pacific Ocean, while rivers east of the divide empty into the Atlantic Ocean or Gulf of Mexico&amp;lt;\/p&amp;gt;\n&amp;lt;!-- \/wp:paragraph --&amp;gt;&lt;\/div&gt;\" data-gt-translate-attributes='[{\"attribute\":\"data-cmtooltip\", \"format\":\"html\"}]'>Continental Divide<\/span>.
