Tropical Storm "Jose" formed September 5, 2017 over the open waters of Atlantic Ocean as the 10th named tropical cyclone of the 2017 Atlantic hurricane season. Three days later, Jose is a powerful, Category 4 hurricane following almost the same path that devastating Hurricane "Irma" took while approaching the Leeward Islands just a few days ago. Heavy rainfall produced by this storm will maintain any ongoing flooding and may cause additional life-threatening flooding. In addition, Jose will bring powerful winds to already devastated islands and a new round of life-threatening swells.
A Hurricane Warning is in effect for Barbuda and Anguilla, Sint Maarten, St. Martin and St. Barthelemy. Preparations to protect life and property should be rushed to completion.
As of 21:00 UTC on September 8, the center of Hurricane "Jose" was located about 540 km (3335 miles) ESE of the northern Leeward Islands and had maximum sustained winds of 240 km/h (150 mph). This places Jose on the upper edge of Category 4 hurricane on the Saffir-Simpson scale.
Jose is moving toward the west-northwest near 28 km/h (17 mph) with a minimum central pressure of 940 hPa. A gradual turn toward the northwest with a decrease in forward speed is expected during the next 48 hours.
Some fluctuations in intensity are possible over the next day or so, and gradual weakening is expected after that.
On the current forecast track, the center of Jose will pass near or east of the northeastern Leeward Islands on Saturday, September 9.
Although it is not expected to make a landfall, islands devastated by Category 5 Hurricane "Irma" will feel extremely dangerous effects of yet another major hurricane.
A Hurricane Warning is in effect for:
- Barbuda and Anguilla
- Sint Maarten
- St. Martin
- St. Barthelemy
A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area, in this case within 24 hours. Preparations to protect life and property should be rushed to completion.

Hazards affecting land
Hurricane conditions are possible within the hurricane watch area on Saturday, September 8 and tropical storm conditions are expected within the tropical storm warning areas by Saturday morning. Tropical storm conditions are possible in the tropical storm watch area in the northeastern Leeward Islands by Saturday morning and in the watch area in the Virgin Islands by Saturday night.
Jose is expected to produce total rain accumulations of 76.2 to 127 mm (3 to 5 inches) in the Leeward Islands from Guadeloupe to Anguilla, with isolated maximum amounts of 203.2 mm (8 inches). Jose is also expected to produce total rain accumulations of 25.4 to 76.2 mm (1 to 3 inches) over the Virgin Islands and Dominica. This rainfall will maintain any ongoing flooding and may cause additional life-threatening flooding.
Swells generated by Jose are expected to affect portions of the Leeward Islands beginning Friday afternoon (local time). These swells are likely to cause life-threatening surf and rip current conditions.
