Hurricane Jose was the fourteenth tropical cyclone, tenth named storm, and seventh hurricane of the annual season that caused moderate damage in the Lesser Antilles in October 1999. Jose developed from a tropical wave several hundred miles east of the Windward Islands on October 17. The depression intensified and was subsequently upgraded to Tropical Storm Jose on October 18. The storm tracked northwestward and was upgraded to a hurricane the following day as it approached the northern Leeward Islands. Jose briefly peaked as a Category 2 hurricane with winds of 100 mph (160 km/h) on October 20. However, wind shear weakened the storm back to a Category 1 hurricane before it struck Antigua. Further deterioration occurred and Jose weakened to a tropical storm before landfall in Tortola on October 21. While located north of Puerto Rico on October 22, the storm turned northward, shortly before curving north-northeastward. Wind shear decreased, allowing Jose to re-intensify into a hurricane while passing east of Bermuda on October 24. However, on the following day, wind shear increased again, while sea surface temperatures decreased, causing Jose to weaken and quickly transition into an extratropical cyclone.
