The cyclone Joaquin strengthened into a Category 1 hurricane in
the Atlantic on Wednesday morning, poised to pound the central Bahamas with
heavy rain and dangerous storm surges in the next day.
Its move after
that -- still hard to predict -- could have flooding implications for an already drenched eastern United States.
Joaquin's center
was spinning 190 miles (305 kilometers) east-northeast of the central Bahamas.
Its maximum sustained winds of 85 mph (130 kph) were mid-range for a Catergory
1 storm, but forecasters predicted it would become stronger.
A hurricane
warning was in effect for the central Bahamas, with the storm's center expected
to be near or over the islands by Thursday before turning north, the U.S. National Hurricane Center said.
More than 10,000 people live on the Bahamian islands most
squarely in the storm's path. Five to 20 inches of rain could fall over much of
the central Bahamas through Friday, with lesser amounts expected over the rest
of the country, the center said.
"Preparations
to protect life and property should be rushed to completion," the
hurricane center said about the Bahamas on Wednesday.
Rain and winds
aren't the only concerns: Dangerous storm surges -- with water levels as high
as 4 feet above normal tides -- are possible on the Bahamian coasts.
Swells from
Joaquin also will affect the southeastern U.S. coast by Friday, potentially
creating life-threatening rip currents, the hurricane center said.
A U.S. landfall?
A hurricane hasn't made landfall in the
eastern United States since Hurricane Arthur hit North Carolina in 2014. That
could change with Joaquin.
Forecasters
expect Joaquin to turn north after the Bahamas, but they have low confidence in
predicting the path after that. Many U.S. computer forecast models predict a
hit on the East Coast next week, anywhere from North Carolina to New York's Long
Island.
One
European-based model predicts the storm going out to sea instead.
"We simply
don't know if it's going to go left into America or right and pass
Bermuda," CNN meteorologist Chad Myers said.
Significant rain possible for Mid-Atlantic next
week
Landfall or not, Joaquin at the very
least could send significant rainfall to the East Coast, where some states
already were dealing with flood threats from separate systems this week.
"There is
so much tropical moisture, we will get 10 inches of rainfall in the
Mid-Atlantic (in the next seven days) -- and that's with a miss," Myers
said. "If we get a hit ... that number may double."
Waterlogged East
Heavy rains hit the Mid-Atlantic and New
England this week, and 2 to 6 inches of rain were still expected to fall in New
England on Wednesday.
Large portions
of Vermont, New Hampshire and Maine were under flood watches or warnings
Wednesday afternoon.
Flooding made
some streets impassable in Portland, Maine. Several cars were stalled on one
street there after their drivers tried to drive through standing water, CNN affiliate
WMTW reported.
