Interestingly, these hurricanes are directly linked to one of the driest places on Earth – the Sahara desert. âThings are unfortunately shaping up to be an active hurricane season in the Atlantic, which is probably not what people are wanting to hear,â says Phil Klotzbach, a meteorologist at Colorado State University who specializes in Atlantic Ocean hurricanes.
The season has already begun at a breakneck pace.

The interaction between the hot dry air of the Sahara and the cooler, more humid air from the Gulf of Guinea to its South forms what’s known as the African easterly jet, which blows from east to west across Africa. Tropical waves interact with the warm equatorial water of the Atlantic as they head west, triggering columns of warm moist air to rise from the ocean. As they blow off the west coast of Africa past Cape Verde, the 2015 study showed that the amount of cloud coverage at that point can predict whether or not these tropical waves will become hurricanes a week or two later. Research has shown that most of the monster storms that hit the US and Canada start out as a distinct weather pattern in the atmosphere over western Africa, specifically a spot off the coast of the African Cape Verde islands. 2020 National Geographic Partners, LLC.

According to Price, only 10 percent of the 60 disturbances originating in Africa every year turn into hurricanes – but the ones that do have the opportunity to gather energy as they cross the Atlantic, which makes them so powerful that they’re more likely to hit the US and even Canada.

However, he notes that this will likely dissipate by mid-August. Colorado State University, which puts out its own seasonal hurricane forecasts, predicts that four major hurricanesâhurricanes Category 3 or higher with winds surpassing 111 miles per hourâwill take shape this year. A number of climactic conditions can influence how easily hurricanes form, but they essentially boil down to temperature and wind. Last year, warm September waters in the Caribbean Sea allowed Hurricane Dorian to dump a devastating amount of rain over the Bahamas. Researchers around the world are now working on better being able to predict which of these disturbances is worth watching and preparing for. Currently, Atlantic surface waters are the fourth warmest theyâve been since NOAA began keeping records in 1982. Warm water acts like fuel for hurricanes, and sea surface temperatures so far this year along the East Coast, Gulf of Mexico, and Caribbean Sea are well above average. The interaction between the hot dry air of the Sahara and the cooler, more humid air from the Gulf of Guinea to its South forms what’s known as the African easterly jet, which blows from east to west across Africa. Most hurricanes that hit the eastern United States begin as bands of thunderstorms known as tropical waves off the western coast of Africa.
Itâs still unclear how much a lack of data will impact our ability to prepare for major hurricanes.
Hereâs why.
