Florence was another 1,000-year rain event. Is this the new normal as the planet warms?
Over a massive region of southeast North Carolina and northeast South Carolina, Florence produced an extraordinary rainstorm that statistically has a 1-in-100 chance of occurring each year. Over substantial areas, the deluge had a 0.1 percent chance of happening, what is known as a 1,000-year event.
These exceptional rainfall events keep happening and appear to be part of a trend toward more extreme tropical rainmakers, probably connected to climate change.
Since August 2017, three hurricanes have set rainfall records for tropical weather systems in four states.
First came Harvey, which dumped an unheard-of five feet of rain in Texas last August. No storm in recorded history had produced so much water in the United States. In all, the hurricane and its remnants generated 33 trillion gallons of water over the country, enough to engulf Houston in a tank of water 3.1 miles high.
Then came Lane in August, which bombarded the Big Island with more than 50 inches, becoming Hawaii’s rainiest tropical storm.
As a point of exclamation, Florence slammed into the Carolinas over the past week, setting tropical storm rainfall records in two states, surpassing 20 inches in South Carolina and 35 inches in North Carolina. Ryan Maue, meteorologist with weathermodels.com, tweeted that the storm dispensed 11 trillion gallons of rainfall along the way.
Florence’s rainfall in North Carolina was the most for any tropical weather system north of Florida along the East Coast on record, and fourth most for any state.
