As of December 22, 2019, The National Oceanic and Atmospheric Administration (NOAA) identified 21,424 severe weather events (excluding tornadoes). That figure is up sharply from the 17,823 severe weather events reported in 2018.

A look at their map of these events (Figure 1) shows that virtually every region of the country experienced severe weather.
NOAA also identified 10 weather and climate disaster events with losses exceeding $1Billion each across the United States (as of October 8).
“… these events resulted in the deaths of 39 people and had significant economic effects on the areas impacted. The 1980–2018 annual average is 6.3 events (CPI-adjusted); the annual average for the most recent 5 years (2014–2018) is 12.6 events (CPI-adjusted).”

Tornadoes increased from 1,169 in 2018 to 1,661 in 2019, That’s an increase of 42%, Was 2019 an anomaly or will this trend continue in 2020?
There were 18 named storms in 2019, 6 of which were classified as hurricanes. Three hurricanes were classified as intense with severe damage. While named storms increased from the 15 reported in 2018, the number of hurricanes decreased from 8 in 2018 to 6 in 2019.
According to the National Interagency Fire Center, the number of wildfires decreased from 55,911 in 2018 to 49,215 in 2019. Wildfires in 2019 burned over 4,576,321 acres.
It is harder to get accurate statistics of inland river flooding than flooding caused by hurricanes and tropical storm in coastal areas.
According to the Center for Disaster Philanthropy, “There were three major rounds of flooding between March and September. In many cases, communities flooded more than once, with barely any time in between to clean up or prepare for another flood. Spring flooding – March through May — is not unusual given snow melt, rising temperatures and rain. But parts of the Midwest and northern U.S. states were hit with a “bomb cyclone” this year that dropped immense amounts of snow and rain in a short period of time.”
There were at least 132 earthquakes in the United States and Mexico of at least 7.0 magnitude recorded in 2019. Most of these occurred from Alaska down the west coast (Figure 3).
So, what insights can we gain from these gloomy statistics?
While real risk assessment must be done locally, looking at the overall picture, most areas of the country will probably experience events where significant numbers of people will be displaced or need to be evacuated.
All communities should be prepared for mass casualty events and have enough multi-patient transport capacity to handle hospital and nursing home evacuations on top of the possible medical surge caused by these types of events.
Many of the events we experienced in 2019 were of significant size and impacted large areas. Therefore, mutual aid agreements for ambulances and shelters may not be able to provide the necessary assets since they will have to dedicate them to their own situations.
Let’s hope that 2020 brings fewer disasters than 2019. But let’s be prepared if it doesn’t.
