As hurricane season gets underway in the Atlantic, GIS is being use to better prepare communities and property from the devastating effects of storms.

This animated satellite view of the Atlantic Basin shows hurricanes Sally and Paulette, along with tropical storms Rene and Teddy, and tropical depression Twenty-One (which was named later in the day on September 14, 2020 as Tropical Storm Vicky).

Hurricane Michael was determined to be the fourth Category 5 storm to make landfall in the United States.

Warmer Oceans Will Make Hurricanes More Intense

Geo Contributor

Since hurricanes draw their energy from ocean heat, warmer waters can increase both their intensity and duration.

Slower Hurricanes Means More Dangerous Hurricanes
