The year 2023 saw a record number of billion-dollar natural disasters, totaling at least $92.9 billion dollars in damage, according to the National Oceanic and Atmospheric Administration (NOAA). [1] These 28 natural disasters included:
17 severe weather/hail events
2 tropical cyclones, including Hurricane Idalia and Typhoon Mawar
1 winter storm/cold wave event
1 wildfire event in Hawaii
1 drought/heat wave event
Of these, the 10 largest disasters caused a whopping $56.6 billion dollars in damage, along with more than 400 deaths and 200 injuries. These disasters spanned the entire country and damaged thousands of homes, which is why it is so important for homeowners to be properly insured.
But keep in mind homeowners insurance excludes damage caused by certain natural disasters, like floods and earthquakes, so homeowners may need to purchase additional coverage to make sure they are fully protected from storm damage.

Number of deaths: 13
Number of injuries: 17
Cost of damage: $6 billion
