Sunday’s rainfall almost certainly marked the last significant precipitation of 2019 for the greater Houston area. The region experienced some extreme rainfall, punctuated by Tropical Storm Imelda in September. But overall, Houston came in near normal with annual rainfall—receiving a total of 51.93 inches at Bush Intercontinental Airport (the region averages just north of 48 inches per year). The wettest year on record came in 2017, driven by Hurricane Harvey, with 79.69 inches. Here’s the climate graphic, with Houston’s rainfall totals on the bottom:
The story is considerably more interesting to the east of Houston, in Beaumont, which bore the brunt of Imelda. That region, based upon its official monitoring station at Jack Brooks Regional Airport, has recorded 85.46 inches of rain in 2019. But this ranks only third in annual totals, behind 2017 (104.30 inches) and 2018 (88.75 inches), based on 117 years of data.
