The ninth named storm of the 2016 hurricane season formed at 11 a.m. Monday, the National Hurricane Center said. Tropical Storm Ian was moving toward the northwest with winds of 40 mph — minimal tropical storm force — and was not expected to be a threat to land. NHC forecasters predicted Ian would top out as a 60 mph tropical storm on Thursday as it moves over the open Atlantic.
Meanwhile, Invest 93L was in the Bahamas and moving toward the Florida peninsula. Wind shear over the Bahamas was running at a relatively high 25 knots — not conducive for development, according to NHC forecasters. Still, they gave it 10 percent chance of becoming a depression or storm over the next two- to five days.
“Locally heavy rainfall is possible over portions of the central and northwestern Bahamas today, and portions of the Florida peninsula on Tuesday,” NHC Senior Hurricane Specialist Richard Pasch said.
Rain chances in the Palm Beach area range from 60 percent Monday to 70 percent on Tuesday.
“The eventual solution of the trough will surely require further adjustments to the overall
forecast scenario for the short term depending on when the trough reaches the Florida peninsula,” National Weather Service forecasters in Miami said. “Models suggest the trough could actually move into central Florida by late Tuesday, which may keep a rather wet pattern across the area through Wednesday morning.”
