MIAMI (AP) -- Hurricane Michael gained strength Monday and
is expected to keep growing stronger ahead of an expected midweek strike on
Florida's Panhandle, forecasters said.
Michael could become a major hurricane with winds topping
111 mph by Tuesday night before the anticipated landfall Wednesday on the
Panhandle or Big Bend, according to the National Hurricane Center.
Since the storm will spend two to three days over the Gulf
of Mexico, which has very warm water temperatures and favorable atmospheric
conditions, "there is a real possibility that Michael will strengthen to a
major hurricane before landfall," Robbie Berg, a hurricane specialist at
the Miami-based storm forecasting hub, wrote in an advisory.
Michael's large size, strong winds and heavy rains could
produce hazardous flooding along a stretch of Florida's Gulf coast with many
rivers and estuaries where seawater pushed ashore by a hurricane could get
trapped, said Hurricane Center director Ken Graham.
"This is a part of the Gulf of Mexico that is
incredibly vulnerable to storm surge," Graham said.
Parts of Florida's curvy Big Bend could see up to 12 feet of
storm surge, while Michael also could dump up to a foot of rain over some
Panhandle communities as it moves inland, forecasters said.
Mandatory evacuation orders were issued for residents of
barrier islands, mobile homes and low-lying coastal areas in Gulf, Wakulla and
In a Facebook post Monday, the Wakulla County Sheriff's
Office said no shelters would be open because Wakulla County shelters were
rated safe only for hurricanes with top sustained winds below 111 mph. With
Michael's winds projected to be even stronger than that, Wakulla County
residents were urged to evacuate inland.
"This storm has the potential to be a historic storm,
please take heed," the sheriff's office said in the post.
By 5 p.m. Monday, Michael's top sustained winds were around
80 mph as it headed north at 9 mph.
The storm was centered about 30 miles off the western tip of
Cuba and about 520 miles south of Apalachicola, Florida. Hurricane-force winds
extend outward up to 35 miles from the storm's center and tropical storm-force
winds extend outward up to 175 miles.
Michael was lashing western Cuba late Monday morning with
heavy rains and strong winds, according to the hurricane center. Forecasters
warned that the storm could produce up to a foot of rain in western Cuba,
potentially triggering flash floods and mudslides in mountainous areas.
Florida Gov. Rick Scott has issued an order for a state of
emergency for 35 counties, from the Panhandle through to Tampa Bay, freeing up
resources and activating 500 members of the Florida National Guard. He urged
residents to quickly wrap up final storm preparations Monday, calling it a "monstrous
storm" with great destructive potential. He also waived tolls in a move to
help coastal dwellers leave.
Also Monday, Gov. Kay Ivey in neighboring Alabama signed an
emergency declaration for her entire state, in anticipation of widespread power
outages, wind damage and heavy rain.
Aside from causing power outages, flooding and property
damage, Michael could also worsen a toxic algae bloom that has plagued Florida's
beaches for a year. The red tide in the Gulf of Mexico off southwest Florida
that began last October after Hurricane Irma swept up the state has killed
massive amounts of marine life and caused respiratory irritations in people.
The bloom has spread to Florida's Panhandle and the Miami area.
