Hurricane Isaias caused major damage during a historically quiet Atlantic season

Hurricane Isaias caused major damage during a historically quiet Atlantic season

Hurricane Isaias struck the U.S. Gulf Coast as a Category 2 storm on Saturday, bringing winds of up to 105 miles per hour and torrential rain.

It spawned tornadoes, destroyed buildings and brought down power lines across the region.

At least four people had died by Tuesday, and thousands remained without power.

Isaias was the Atlantic season’s first hurricane and the latest first hurricane on record, after a period of unusually low activity.

El Niño has made Atlantic hurricanes harder to form by creating strong upper-level winds that can break storms apart, while the Pacific has seen many hurricanes.

Isaias formed when those winds briefly weakened near the Gulf Coast and warm Atlantic water helped it strengthen quickly.

Another storm this season would likely affect the Gulf Coast, while high wind shear makes hurricanes in the Caribbean less likely; experts say even a quiet season can still bring severe damage.
