U.S. Hit by 16 Billion-Dollar Disasters This Year, So Far

September will be remembered as a month of extremes: Historic wildfires burned across the West, unprecedented tropical activity churned up the Atlantic, and parts of the country saw record heat.

What’s more, the first nine months of 2020 brought a record-tying 16 billion-dollar weather disasters to the nation, according to scientists with NOAA’s National Centers for Environmental Information. Six of those events —  western wildfires, a Western/Central U.S. drought and heatwave, Hurricane Sally, Hurricane Laura, the Midwest derecho and Hurricane Isaias — have all occurred since June.

Here are the climate highlights for September and 2020 to date:

Climate by the numbers

September 2020

The average September temperature across the contiguous U.S. was 66.0 degrees F — 1.1 degrees above average — which fell into the warmest third in the 126-year record. While parts of the country saw cooler-than-average temperatures, including the Plains and Deep South, much of the West was steamy.

California and Oregon saw their hottest September on record; Arizona and Nevada had their second hottest.

The average precipitation last month was 2.38 inches (0.11 of an inch below average), which ranked in the middle third of the record. Some locations did see a wetter-than-normal September, including the Deep South and Southeast, due mainly to Tropical Storm Beta and Hurricane Sally. In fact, Georgia has its ninth-wettest September on record.

Year to date (YTD) | January through September 2020

The year-to-date average temperature for the contiguous U.S. was 57.3 degrees F — 2.3 degrees above the 20th-century average and the sixth-warmest YTD on record. Florida experienced its hottest YTD, while Arizona, Massachusetts, New Jersey and Rhode Island saw their third hottest.

In terms of precipitation, the YTD total was 24.08 inches (0.88 of an inch above average) and ranked in the middle third of the record.

Mississippi, North Carolina, Tennessee and Virginia saw their third-wettest YTD on record, while Utah and Colorado recorded their driest and second-driest YTD, respectively.

Billion-dollar disasters to date

From January through the end of September of this year, the U.S. has experienced 16 weather and climate disasters with losses exceeding $1 billion each. Eleven were due to severe storms—which occurred across more than 30 states—and the remaining 5 comprised one wildfire, one drought and three tropical cyclones.

With 16 disasters so far, 2020 has already tied with 2011 and 2017 for the largest number of disasters in a calendar year. This is also a record sixth-consecutive year where 10 or more billion-dollar disasters have struck the U.S.

More notable climate events

  • Wildfires wreaked havoc across California: Since mid-August, more than 4 million acres have burned across California, breaking the statewide burn record set in 2018 by more than 2 million acres. Five of the top six largest wildfires on record in California (dating to 1932) burned between August and the end of September.
  • The tropics were very active: The Atlantic hurricane season continued at a record pace last month. In September alone, 10 named storms formed — Nana, Omar, Paulette, Rene, Sally, Teddy, Vicky, Wilfred, Alpha and Beta. For the first time since 1971, five named storms churned in the Atlantic Basin at the same time.

  • Drought got worse: According to the U.S. Drought Monitor report, 42.6% of the contiguous U.S. was in drought, up about 3 percentage points from the beginning of September. Drought conditions expanded or intensified across much of the Northeast and the western half of the contiguous U.S.
