Tropical Storm Imelda could become second hurricane to hit Caribbean in days

Imelda is forecast to strengthen as Hurricane Humberto continues to bring strong winds to region

Hurricane Humberto continues to churn in the Sargasso Sea north of the Caribbean, and held on as a powerful category 4 storm on Sunday. Just a day earlier, Humberto briefly reached category 5 status with 160mph sustained winds before it weakened slightly on Sunday.

Humberto is likely to remain offshore and track west of Bermuda on Monday night into Tuesday, but its strength will still send large swells, life-threatening rip currents and surf across the Lesser Antilles and the US east coast over the coming days.
