Rainfall on Sunday totaled 4.56 inches at Key West International Airport, breaking the previous record of 2.89 inches, which was set in 1872.
In fact, this will also go down as the wettest February day in history. The previous record of 4.04 inches was set on Feb. 28, 1954.
The rainfall was the result of a few factors. Late Saturday evening, an upper-level disturbance developed a trough of low pressure over the Yucatan channel. On Sunday, this trough pushed northeast towards the Florida Keys and the Florida Peninsula. Combined with copious amounts of atmospheric moisture and adequate instability, the trough became the focus point for a large area of showers and thunderstorms.
Most of the Keys received generous amounts of rain, but the highest totals were in Key West. No flood advisories or warnings were issued for Key West, but a couple reports were received concerning minor flooding of low-lying areas around the island. By Monday morning, the heaviest rainfall had moved east of the Florida Keys.
