Hurricane Dorian is moving over the US Virgin Islands and toward Puerto Rico. It could hit Florida as a major hurricane on Monday.
Dorian is the fourth named storm in this Atlantic hurricane season, which is projected to see above-average activity.
As our planet warms, such storms are forecast to become stronger, slower, and wetter.
Storms with heavy rainfall, like Hurricane Barry earlier this year and Hurricane Harvey in 2017, can cause devastating flooding and infrastructure damage even without extreme winds.

Hurricane Dorian is hitting the US Virgin Islands as a Category 1 storm and approaching Puerto Rico. It could hit Florida as a major hurricane on Monday.
Dorian threatens to flood Caribbean islands and dump up to 8 inches of rain along parts of the southeastern coast of the US.
The National Oceanic and Atmospheric Administration (NOAA), which recently revised its forecast for this year’s Atlantic hurricane season, now projects a 45% chance that this year will see above-average activity. That could mean five to nine hurricanes in the Atlantic, with two to four of those expected storms becoming major hurricanes (defined as Category 3 or above, with winds greater than 110 miles per hour).
On average, the Atlantic sees six hurricanes during a season, with three of them developing into major hurricanes. Hurricane season peaks August through October and ends on November 30.

Scientists can’t definitely say whether Hurricane Dorian or other individual storms this year are directly caused by climate change, but warming overall makes storms and hurricanes more devastating than they would otherwise be.
That’s because higher water temperatures lead to sea-level rise, which increases the risk of flooding during high …read more
