Severe convective storms – storms associated with thunder, lightning, heavy rain, hail, strong winds and sudden temperature changes – caused USD 35 billion (nearly 70%) in insured losses worldwide in the first half of 2023. This means that insured losses are almost twice as high in a six-month period as the annual average of the last ten years (USD 18.4 billion).
