The impact of hurricanes in the United States is an average of 20 deaths and $5.1 billion per year (excluding the 2005 season). On average, ten tropical storms form during the Atlantic hurricane season, with 6 becoming hurricanes and 2-3 becoming major hurricanes. However, tropical cyclone activity in the Atlantic is cyclical, with a time period of multiple decades. Since the mid-1990s, activity increased sharply and this period of heightened activity could last until the 2020s or longer.
