Tropical Storm Bonnie became the second named storm of the 2022 Atlantic hurricane season on Friday, hours after strong winds and heavy rain began to hit Nicaragua and Costa Rica, bringing the risk of life-threatening flash floods and mudslides.
The storm was named after reaching winds of at least 39 miles per hour, but it brought heavy rain and weather warnings to the Caribbean days before Bonnie reached that point.
By Friday, the storm strengthened slightly and moved into the southwestern Caribbean Sea. Bonnie is expected to strengthen further before making landfall Friday night near the Nicaragua-Costa Rica border, where a tropical storm warning has been issued, according to the National Hurricane Center. The storm is expected to move through the region into Saturday.
While the system is expected to weaken as it traverses Central America, it is expected to re-strengthen Saturday as it reaches the warm waters of the eastern Pacific.
Maria Torres, a meteorologist at the Hurricane Center, said Bonnie needed to “maintain a recognizable closed circulation” as it crossed Central America into the Pacific to retain its name. Ms Torres said hurricanes rarely jumped from the Atlantic to the Pacific, the last being Hurricane Otto in 2016.
Jumps in the opposite direction — from the Pacific to the Atlantic basin — are even less common. Ms Torres said no tropical cyclone had kept a complete record as it moved from the eastern Pacific to the Atlantic.
Forecasters are watching two other storms in the Atlantic, one of which is expected to bring heavy rain to the U.S. Gulf Coast this weekend. flood warning Effective in Texas and Louisiana. The other, further east, is expected to slowly follow Bonnie’s path to Central America over the weekend.
Tropical Storm AlexFormed on June 5, it is the first named storm expected to be the “extraordinary” hurricane season, According to the National Oceanic and Atmospheric Administration. If this forecast comes true, 2022 will be the seventh consecutive year of an above-normal season.
This year, meteorologists are forecasting between 14 and 21 named storms for the season, which runs through Nov. 30. Six to 10 of these are expected to become hurricanes, with as many as six expected to intensify into major hurricanes, classified as Category 3 storms with winds of at least 111 mph.
Last year, there were 21 named storms, in A record 30 in 2020Over the past two years, meteorologists have exhausted the list of names used to identify storms in the Atlantic hurricane season, which happened only once in 2005.
The link between hurricanes and climate change becomes clearer every year. Data Display, Hurricanes are getting stronger around the world in the past four years. Over time, a warming planet may experience stronger hurricanes and a higher rate of the strongest storms – although the total number of storms may decline, as factors such as stronger wind shear may prevent Weaker storms form.
Hurricanes also become wetter due to more water vapor in warmer atmosphere; scientists suggest storms like Hurricane Harvey in 2017 Much more rainfall is produced than would be produced without human influence on the climate. In addition, rising sea levels are causing higher storm surges—the most damaging element of tropical cyclones.
