Tropical Storm Kate Forms in the Atlantic
The storm is the 11th named storm of a busy hurricane season.,
As residents along the Louisiana coast surveyed the damage left after Hurricane Ida came ashore, and a day after Tropical Storm Julian formed and was quickly downgraded, Tropical Storm Kate formed in the Atlantic Ocean on Monday, becoming the 11th named storm of a busy hurricane season.
The National Hurricane Center said Tropical Storm Kate would move over the open waters of the central Atlantic Ocean. There were no coastal watches or warnings in effect for the storm.
It’s been a dizzying few weeks for meteorologists who monitored several named storms that formed in quick succession in the Atlantic, bringing stormy weather, flooding and damaging winds to parts of the United States and the Caribbean. In addition to Ida and Julian, in the last few weeks Tropical Storm Fred made landfall in the Florida Panhandle, Hurricane Grace hit Haiti and Mexico, and Tropical Storm Henri knocked out power and brought record rainfall to the Northeastern United States.
The links between hurricanes and climate change are becoming more apparent. A warming planet can expect stronger hurricanes over time, and a higher incidence of the most powerful storms — though the overall number of storms could drop, because factors like stronger wind shear could keep weaker storms from forming.
Hurricanes are also becoming wetter because of more water vapor in the warmer atmosphere; scientists have suggested storms like Hurricane Harvey in 2017 produced far more rain than they would have without the human effects on climate. Also, rising sea levels are contributing to higher storm surge — the most destructive element of tropical cyclones.
A major United Nations climate report released in August warned that nations have delayed curbing their fossil-fuel emissions for so long that they can no longer stop global warming from intensifying over the next 30 years, leading to more frequent life-threatening heat waves and severe droughts. Tropical cyclones have likely become more intense over the past 40 years, the report said, a shift that cannot be explained by natural variability alone.
Ana became the first named storm of the season on May 23, making this the seventh year in a row that a named storm developed in the Atlantic before the official start of the season on June 1.
In May, scientists with the National Oceanic and Atmospheric Administration forecast that there would be 13 to 20 named storms this year, six to 10 of which would be hurricanes, and three to five major hurricanes of Category 3 or higher in the Atlantic. In early August, in a midseason update to the forecast, they continued to warn that this year’s hurricane season will be an above average one, suggesting a busy end to the season.
Matthew Rosencrans, of the National Oceanic and Atmospheric Administration, said that an updated forecast suggested that there would be 15 to 21 named storms, including seven to 10 hurricanes, by the end of the season on Nov. 30. Kate is the 11th named storm of 2021.
Last year, there were 30 named storms, including six major hurricanes, forcing meteorologists to exhaust the alphabet for the second time and move to using Greek letters.
It was the highest number of storms on record, surpassing the 28 from 2005, and included the second-highest number of hurricanes on record.
