Final Storm Precipitation Totals (6/6 - 6/10 2019)


Good Tuesday afternoon to everyone, we are putting the final wraps on a storm system that impacted the Western Carolinas with excessive rainfall totals and flash flooding...


To recap the synoptic players: We have a strong upper low that ejected from the Four Corners Region into the Southern Plains and eventually into the Southeast US. WIth a blocking high over Southeast Canada, it slammed the brakes on the upper low and as a result it crawled eastward before finally shearing out on Monday.


To go along up the dynamics, we had abundant tropical moisture that had origins in the NW Caribbean and Gulf of Mexico. This feature never classified as a tropical depression but the impacts were the same regardless. Then at the surface layer, easterly and southeast winds created a low level upslope component that aided in the very heavy rainfall that occured.





The vast majority of the coverage area was impacted significantly by this storm event...with the highest impacts coming roughly along and north of Interstate 40. By far the hardest hit counties were Alexander, Burke, Caldwell, Catawba and Lincoln Counties where widespread 6-10+ inch totals were recorded. Even outside of the hardest hit areas, sections of McDowell, Rutherford and Cleveland Counties had in general 4-8 inches of rain. Due to the dry conditions leading prior to this storm, those areas were able to handle their rainfall totals without dealing with flash flooding. Below is a doppler radar image going back to Thursday...







While doppler radar estimates were impressive in itself, we have acquired rainfall totals that exceed what the estimates are (which is common). This is why we always value getting reports on the ground rather than always relying on radar data... Here is a map of select rainfall totals going back to Thursday...this data was taken from local CoCoRaHS observers along with local COOP stations. The highest totals generally follow in line with the doppler estimates. The highest amounts lie in Alexander, Caldwell and Catawba Counties...with the Ellendale Community in Western Alexander County picking up a whopping 16.70 inches of rain. That is essentially four months of rainfall in four days...





Impacts continue across the areas with road closures, bridges washed out, sinkholes, landslides and other impacts. These impacts will continue over the foreseeable future.
