The bottom two images show the average return date for hurricanes and major hurricanes. On average, Tampa Bay would see a hurricane pass within 50 nautical miles every ten years. Tampa Bay would see a major (category 3 or higher) hurricane pass within 50 nautical miles every 33 years. The last major hurricane to make landfall within 50 miles of Tampa Bay was in 1921!
