NOAA forecasts an above-normal and possibly very active Atlantic hurricane season in 2013 in their May 23 outlook. They give a 70% chance of an above-normal season, a 25% chance of an near-normal season, and 5% chance of a below-normal season. They call for 16.5 named storms, 9 hurricanes, 4.5 major hurricanes, and an ACE index 162% of normal. This is well above the 1981 - 2010 average of 12 named storms, 6 hurricanes, and 3 major hurricanes.

The recent catastrophic EF-5 tornado in Oklahoma has prompted me to revisit a blog I posted in April 2011 (ironically that blog was posted just two weeks prior to the deadly tornado outbreak on April 27-28 of that year). This blog updates the lists of all known F-5 and EF-5 tornadoes and other statistics concerning the deadliest tornadoes on record in U.S. and world history.
