Irma finally weakened to just a big storm, 10 days after it became a hurricane and started on a destructive and powerful path that killed 40 people in the Caribbean and the Southeastern United States.
Irma was producing very heavy rain across the Southeast, leading to flash floods and rapid rises in creeks, streams and rivers. The hurricane center said that significant river flooding would persist over the Florida peninsula for several days and that parts of Georgia, South Carolina and north-central Alabama remained vulnerable to flash floods.
In Irma’s wake, meanwhile, lay a trail of devastation from the Cape Verde Islands to Georgia. Irma was so strong and so robust that it seemingly set a record for the number of records it set. According to Phil Klotzbach, a noted atmospheric research scientist at Colorado State University:
- When Irma reached Category 5 — the strongest there is — it stayed there for more than three days, the longest run since forecasters began using satellites to monitor tropical storms more than a half-century ago.
- Irma kept blowing 185-mph maximum sustained winds for 37 hours — the longest any cyclone has ever maintained that intensity anywhere on Earth since records started being kept.
- Irma generated the most accumulated energy by any tropical cyclone in the Atlantic tropics on record.
But if there’s one statistic that sums Irma up, it’s this one: It generated enough accumulated cyclone energy — the total wind energy generated over a storm’s lifetime — to meet the National Oceanic and Atmospheric Administration’s definition of an average full Atlantic hurricane season.
About 7.5 million customers remained without power in Florida late Monday. Almost 1½ million had no power in Georgia, which experienced the oddity of tropical storm warnings over Atlanta, more than 800 miles from where Irma made its first U.S. landfall. “This will be the largest ever mobilization of [electric] line restoration workers in this country, period, end of story,” Tom Bossert, President Donald Trump’s homeland security adviser, told reporters Monday.
The U.S. military spread far and wide in what Bossert called “the largest-ever mobilization of our military in a naval and marine operation. … We have the largest flotilla operation in our nation’s history to help not only the people of Puerto Rico, the people of the U.S. Virgin Islands, but also St. Martin and other non-U.S. islands affected,” he said.
