More Than Texas Floods: Four States Affected by CATs 81 and 82

PCS actively monitored two wind and thunderstorm events during the last week of May. CAT 81 was designated for May 23 to 28. The front, which caused storms that resulted in severe flooding in Texas, remained stationary for several days. Another front, which formed on May 28 and continued through May 29, moved in the same direction and affected the same states. This second front was designated CAT 82. Two fronts moving across the same region within a short span of time resulted in a PCS designation overlap for May 28 and four states. Here’s how the two CATs intersected:

  • CAT 81 began as a cold front/dry line across western Texas, with the main low pressure located in southeast Colorado and a warm front extending across northern Texas.
  • The warm front shifted northward over the following few days, with the main low pressure and cold front/dry line remaining stationary in the western Texas region.
  • On the afternoon of May 28, the system fully broke away and shifted off to the east as a new dry line associated with CAT 82 formed in western Texas. The second front affected Colorado, Kansas, Oklahoma, and Texas. Because the front associated with CAT 81 had moved on to the east, PCS designated CAT 82 as a separate event.

PCS reviews meteorological sources as well as feedback from insurers to determine the dates and states that correlate to each storm front. We’re here if you have questions. For more information, please contact me at 201-469-3144 or
