Hurricane Drought Hits a New Record

Posted by K R on

Saturday was a quiet day across the Gulf of Mexico, but not one without note, because a strange record was set: It has been 1,048 days since a hurricane developed in or entered the Gulf. That is the longest streak in the past 130 years, since formal record-keeping began in 1886. The Atlantic hurricane season starts in June and lasts through the end of November. But the last storm in the Gulf was Hurricane Ingrid, which made landfall in northeastern Mexico in September 2013. "You have to have conditions just right for a hurricane to form, and the conditions haven't been ideal in the Gulf of Mexico in the last two years," says Robbie Berg, a hurricane specialist at the National Hurricane Center. The last long Gulf hurricane drought was from October 1, 1929, to August 13, 1932. It was broken by Hurricane 2, which came ashore in Freeport, Texas, as a category 4 storm. Hurricanes usually form when ocean water has been warmed over the summer months to around 25 degrees Celsius or higher. As humid air and clouds accumulate, light, sweeping winds moving westward from Africa can steer the clouds across the mid-Atlantic toward the Gulf. In some cases, the mass of moisture can begin rotating as it advances. This early stage is known as a tropical depression, which can strengthen to become a tropical storm if the wind direction and speed throughout all levels of the atmosphere remain relatively constant. To be considered a category 1 hurricane or higher, the wind speed inside the rotating storm needs to be at least 119 kilometers per hour (74 miles per hour). Read More: Scientific American
