DISCUSSION AND OUTLOOK
----------------------
At 900 AM MDT (1500 UTC), the center of Hurricane Bonnie was located
near latitude 16.1 North, longitude 109.0 West. Bonnie is moving
a little slower toward the west near 12 mph (19 km/h). A westward
to west-northwestward motion is forecast through the week with an
increase in forward speed beginning on Thursday.
Maximum sustained winds have increased to near 105 mph (165 km/h)
with higher gusts. Slight fluctuations in strength are possible
today. Gradual weakening is forecast to commence later tonight
continue through Saturday. Bonnie is expected to become a
post-tropical cyclone in a few days.
Hurricane-force winds extend outward up to 10 miles (20 km) from the
center and tropical-storm-force winds extend outward up to 80 miles
(130 km).
The estimated minimum central pressure is 970 mb (28.65 inches).
HAZARDS AFFECTING LAND
----------------------
SURF: Swells generated by Bonnie will continue to affect portions
of the coast of southwestern Mexico through today. These swells
are likely to cause life-threatening surf and rip current
conditions. Please consult products from your local weather
office.

Hurricane Bonnie Discussion Number 36
NWS National Hurricane Center Miami FL EP042022
900 AM MDT Wed Jul 06 2022
There's been quite a bit of improvement this morning in Bonnie's
inner core structure and a cloud-filled eye reappeared in first
light visible imagery. A 1216 UTC SSMI/S microwave pass revealed a
partial eyewall with about 70 percent coverage in the north through
southwest quadrants and recent enhanced infrared images show Bonnie
attempting to close off a white ring with -77C cloud top
temperatures. The initial intensity is raised to 90 kt for this
advisory, in accordance with the subjective satellite intensity
estimates. Bonnie's surface wind profile has been reduced in all
quadrants based on a 0448 UTC METOP-B scatterometer overpass and
subsequently has been adjusted downward in the forecast.
The predicted decrease in vertical wind shear has allowed Bonnie to
make a comeback. This sudden intensification is expected to be
temporary, however, and Bonnie should begin to weaken slowly on
Thursday while it begins its track over decreasing oceanic surface
temperatures. Dry, stable environmental conditions will also
contribute to its eventual dissipation by late this weekend. The
NHC forecast is again adjusted downward from the previous one and is
based mainly on the global models and the IVCN intensity aid.
Bonnie should degenerate to a remnant low in 4 days, if not earlier,
and open into a trough of low pressure early next week.
Bonnie's moving westward, or 280/10 kt within the westerly
mid-level steering flow of a subtropical ridge to the north. There
are no changes to the forecast track philosophy. The cyclone
should continue on a westward to west-northwestward fashion
with an increase in forward speed commencing Thursday. The
official forecast is essentially the same as last night's advisory
and agrees with the TVCE multi-model consensus.
Although Bonnie will be moving farther away from the southwestern
coast of Mexico, rough surf and the potential for rip currents will
continue to affect portions of the coast of southwestern Mexico
today.
