July Hurricane History

The threat for a tropical storm or hurricane is much higher in July but rather small when compared to the remainder of the Atlantic Hurricane Season.

On average, by the time July ends, two named storms would have formed in the Atlantic Hurricane basin. This is about one-fifth of the number of storms that form in an average year, with the months of August and September seeing the most storm activity.

Any storms that do form will likely develop in three regions of the Atlantic basin: the Gulf of Mexico and northern Caribbean, just east of the Leeward Islands and in an area of the western Atlantic stretching from the Bahamas north along the Florida coast and up to Cape Hatteras.

Last year saw a slightly above average start to the season in June, and things stayed steady for July. Following Andrea and Barry in June, Chantal and Dorian formed in July. Dorian eventually skirted the East Coast of Florida as weak tropical depression in early August.

In 2012, there were no named storms in July. In 2011, there were three named storms in July. In 2010, two named storms formed in July while both the Atlantic Ocean and Gulf of Mexico had no storm development in 2009.

This followed an active 2008 when three named systems, including major hurricane Bertha and hurricane Dolly, formed. Bertha was record setting as it became the longest-lived Atlantic July tropical system on record. Dolly came ashore in extreme southern Texas as an 80-mph hurricane, causing an estimated $1.05 billion in damage.

In record-shattering 2005, the tropics were unusually active with five named tropical systems developing. Of the five named system, three of them, Cindy, Dennis and Emily, became hurricanes. Emily and Dennis both grew into major hurricanes (Category 3 or higher), with Emily growing into a Category 5 monster with an estimated 160-mph top wind speed.
