Both sites have very long periods of record dating back to the late 1800s, so any records would be impressive.<\/p>\n<p><a href=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/07\/vis_markup-1.png\"><img loading=\"lazy\" class=\"size-full wp-image-14828 aligncenter\" src=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/07\/vis_markup-1.png\" alt=\"\" width=\"567\" height=\"397\" srcset=\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/07\/vis_markup-1.png 567w, https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/07\/vis_markup-1-300x210.png 300w\" sizes=\"(max-width: 567px) 100vw, 567px\"\/><\/a><\/p>\n<h3><strong>Today&rsquo;s Flood Threat Map<\/strong><\/h3>\n<p>For more information on today&rsquo;s flood threat, see the map below.
