Serving Nebraska / Covering The World
Another landfall, on the eastern coast of Mexico’s mainland, left at least eight people dead.
And Henri formed on Aug. 16 as a tropical storm off the East Coast of the United States. It strengthened into a Category 1 hurricane but was downgraded before making landfall in Rhode Island, sparing the region the worst of what had been predicted. It thrashed the Northeast with fierce winds and torrential rain, knocking out power to more than 140,000 households from New Jersey to Maine.

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.
The links between hurricanes and climate change are becoming more apparent. A warming planet could expect to have 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.
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 would be an above average one, suggesting a busy end to the season.
Matthew Rosencrans, of the NOAA, 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. Julian is the 10th 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.
