DISCUSSION AND OUTLOOK
----------------------
At 400 PM CDT (2100 UTC), the center of Hurricane Michael was
located near latitude 22.2 North, longitude 85.2 West. Michael is
moving toward the north near 9 mph (15 km/h). A northward to
north-northwestward motion at a slightly faster forward speed is
expected through Tuesday night, followed by a northeastward motion
on Wednesday and Thursday. On the forecast track, the center of
Michael will move into the southeastern Gulf of Mexico this evening,
then move across the eastern Gulf of Mexico Tuesday and Tuesday
night. The center of Michael is expected to move inland over the
Florida Panhandle or Florida Big Bend area on Wednesday, and then
move northeastward across the southeastern United States Wednesday
night and Thursday.

Maximum sustained winds have increased to near 80 mph (130 km/h)
with higher gusts. Steady to rapid strengthening is forecast during
the next day or so, and Michael is forecast to become a major
hurricane by Tuesday or Tuesday night.

Hurricane-force winds extend outward up to 35 miles (55 km) from the
center and tropical-storm-force winds extend outward up to 175 miles
(280 km). A wind gust to 75 mph (120 km/h) was reported at an
observing site in Isabel Rubio in the Cuban province of Pinar del
Rio earlier this afternoon.

The estimated minimum central pressure is 978 mb (28.88 inches).


HAZARDS AFFECTING LAND
----------------------
STORM SURGE:  The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water has the
potential to reach the following heights above ground if peak surge
occurs at the time of high tide...

Indian Pass FL to Cedar Key FL...8-12 ft
Cedar Key FL to Crystal River FL...6-8 ft
Okaloosa/Walton County Line FL to Indian Pass FL...5-8 ft
Crystal River FL to Anclote River FL...4-6 ft
Anclote River to Anna Maria Island FL including Tampa Bay...2-4 ft
Alabama/Florida border to Okaloosa/Walton County Line FL...2-4 ft

WIND:  Hurricane conditions will continue over portions of the
far western Cuban province of Pinar del Rio through this evening.
Tropical storm conditions are expected across the remainder of the
warning areas in Cuba and the Yucatan Peninsula through tonight.

Hurricane conditions are expected within the hurricane warning
area along the U.S. Gulf Coast by Wednesday, with tropical storm
conditions expected by Tuesday night or early Wednesday.  Tropical
storm conditions are expected in the tropical storm warning area by
Tuesday night or early Wednesday, and are possible within the
tropical storm watch area by that time.  Hurricane conditions
are possible within the hurricane watch area by Wednesday.

RAINFALL:  Michael is expected to produce the following rainfall
amounts through Friday...

Western Cuba...4 to 8 inches, with isolated maximum amounts of 12
inches. This rainfall could lead to life-threatening flash floods
and mudslides.

Florida Panhandle and Big Bend across Georgia into South Carolina...
4 to 8 inches, with isolated maximum amounts of 12 inches. This
rainfall could lead to life threatening flash floods.

Florida Peninsula, Florida Keys, North Carolina, portions of the
Mid-Atlantic States, and the southern New England coast...2 to 4
inches with isolated maximum amounts of 6 inches. This rainfall
could lead to life-threatening flash floods.

Yucatan Peninsula...1 to 2 inches.

SURF:  Swells generated by Michael are affecting the south coast of
Cuba and the east coast of the Yucatan Peninsula. Swells are
expected to begin affecting the coast of the eastern and northern
Gulf of Mexico during the next day or so. These swells are likely
to cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.
