Subtropical Storm Debby develops in the Atlantic

Meanwhile, Hurricane Hector is also swirling in the Pacific as an impressively organized Category 4 hurricane.

As of 5 p.m. ET, Hector had winds of 130 miles per hour and was moving to the west at 16 miles per hour.

"Far northern fringes of the hurricane will brush the Big Island Wednesday", forecasters said in an update.

The storm began taking subtropical - not-quite tropical - characteristics, and was named Tuesday morning.

According to the Central Pacific Hurricane Center, the center of the hurricane was located about 225 miles south-southeast of Hilo, or 400 miles southeast of Honolulu.

West of Mexico, Hurricane John was forecast to strengthen into a major hurricane while heading to the northwest parallel to the shore.

Rain: Rains from the deep tropical moisture surrounding Hector could affect the Puna and Kau Districts of Hawaii Island, and some of those rain showers may be locally heavy at times, especially on east and southeast-facing slopes.

The active season in the Pacific contrasts to the relatively quiet season in the Atlantic. None of these storms was a threat to Florida.

Subtropical Storm Debby has formed in the open Atlantic Tuesday with the expectation of not surviving beyond a few days, according to the latest advisory from the National Hurricane Center. All these conditions tend to be associated with quieter Atlantic hurricane season. A turn toward the northeast is forecast by this afternoon, and that motion should continue into Thursday.
