Irma is expected to make landfall along the string of French islands that includes Guadeloupe late Tuesday before heading to Haiti and Florida.

The storm was moving towards the west at 14 miles (22 kilometers) per hour, and is expected to drop between four and eight inches (10 and 20 centimeters) of rain when it hits land.
"These rainfall amounts may cause life-threatening flash floods and mudslides," the NHC warned.
The storm is also is expected to "cause life-threatening surf and rip current conditions."
Irma, which has triggered alarm and alerts from the French West Indies to Florida, comes after of Hurricane Harvey devastated parts of Texas and Louisiana late last month.
