AUSTIN (KXAN) — Another heavy rainstorm swept through Austin this morning, adding to the impressive May rainfall totals we have already recorded.

Through last night, ABIA has totaled 7.41″ of rain this month, ranking 11th for the wettest May on record there. Camp Mabry tallied 6.88″ as of late last night, only enough for the 31st wettest May at that observing station. Additional rain falling today will add to these numbers.

Though this morning’s rain was heavy, it was also brief. Additional rain totals this morning have remained under 0.25″ in most areas. 

This wet May comes courtesy of a weak El Niño pattern in place. El Niño is a multi-year ocean oscillation that features warmer than normal ocean temperatures in the Pacific Ocean near the Equator. This alters global weather patterns, often steering more storms into Texas.

Following two rounds of deadly flooding during the first 8 days of this month, the weather pattern has settled down a bit overall. See this May’s daily rainfall broken down from Camp Mabry (below):
