DISCUSSION AND OUTLOOK
----------------------
At 700 PM EST (0000 UTC), the center of Hurricane Rafael was located
near latitude 23.2 North, longitude 83.2 West. Rafael is moving
toward the northwest near 13 mph (20 km/h). A general northwestward
motion is anticipated tonight. A slower west-northwestward to
westward motion is expected Friday through the weekend. On the
forecast track, Rafael is expected to move away from western Cuba
this evening, and move over the southeastern Gulf of Mexico this
evening and tonight. Rafael is then forecast to move over the
southern Gulf of Mexico for the next few days.
Maximum sustained winds are near 105 mph (170 km/h) with higher
gusts. Rafael is a category 2 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Little change in strength is expected during
the next day or so while Rafael moves over the southeastern Gulf of
Mexico.
Hurricane-force winds extend outward up to 30 miles (45 km) from
the center and tropical-storm-force winds extend outward up to 115
miles (185 km). Wind gusts to tropical-storm force are occurring
in squalls over the Lower and Middle Florida Keys, including a gust
of 66 mph (106 km/h) at the NOAA station at Sand Key.
The minimum central pressure based on NOAA Hurricane Hunter
aircraft data is 966 mb (28.53 inches).
HAZARDS AFFECTING LAND
----------------------
Key messages for Hurricane Rafael can be found in the Tropical
Cyclone Discussion under AWIPS header MIATCDAT3 and WMO header
WTNT43 KNHC and on the web at hurricanes.gov/text/MIATCDAT3.shtml
WIND: Hurricane conditions are expected to continue in portions of
western Cuba for the next few hours. Tropical storm conditions
are expected in parts of west-central Cuba and the lower and middle
Florida Keys through tonight.
RAINFALL: Heavy rainfall will impact areas of the western Caribbean
through early Thursday, particularly across the Cayman Islands and
western Cuba. Rainfall totals of 4 to 8 inches are expected across
portions of western Cuba, with isolated higher totals up to 12
inches in areas of higher terrain. This will lead to areas of flash
flooding and mudslides. Across the Cayman Islands additional
rainfall of 2 to 4 inches is expected.
Rainfall totals of 1 to 3 inches are expected for the Lower and
Middle Florida Keys.
For a complete depiction of forecast rainfall associated with
Hurricane Rafael, please see the National Weather Service Storm
Total Rainfall Graphic, available at
https://www.nhc.noaa.gov/graphics_at3.shtml?rainqpf
STORM SURGE: Storm surge flooding along the coast of Cuba should
subside tonight.
The combination of a 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 could reach the following
heights above ground somewhere in the indicated areas if the peak
surge occurs at the time of high tide...
Dry Tortugas...1-3 ft
Lower Florida Keys...1-2 ft
TORNADOES: A couple of tornadoes are possible through tonight over
the Florida Keys and far southwestern Florida mainland.
SURF: Swells generated by Rafael are expected to affect much of the
western Caribbean during the next day or so and will also spread
across most of the Gulf of Mexico from east to west late this week
into the weekend. These swells are likely to cause life-threatening
surf and rip current conditions. Please consult products from your
local weather office.

Hurricane Rafael Discussion Number 13
NWS National Hurricane Center Miami FL AL182024
400 PM EST Wed Nov 06 2024
The radar and satellite presentation of Rafael continued to improve
after the release of the previous advisory with the eye becoming
quite distinct around midday in geostationary satellite imagery.
An Air Force Reserve reconnaissance aircraft was able to fly a
couple of passes through the center earlier this afternoon and
measured a peak flight-level wind of 104 kt and an extrapolated
minimum pressure of 956 mb. The aircraft was unable to sample the
northeastern quadrant where the maximum winds were likely located.
Therefore, the initial intensity was increased to 100 kt on the
1800 UTC intermediate advisory. The 100-kt initial intensity is
supported by a blend of the various UW/CIMSS objective Dvorak
estimates, and UW/CIMSS SATCON which peaked near that value. Over
the past few hours it appears that an eyewall replacement cycle is
underway as the eye has become less distinct in satellite imagery,
and radar data has shown the erosion of the smaller inner-eyewall.
With the eyewall replacement ongoing, little additional change in
strength is expected before Rafael makes landfall in western Cuba
within the next hour or so. Some weakening is expected as the
storm crosses Cuba, but Rafael is likely to remain a hurricane over
the southeastern and southern Gulf of Mexico during the next few
days. After that time, increasing southwesterly shear and
significantly drier air are likely to result in weakening. As
noted earlier, there are some models that take Rafael southwestward
late in the period over the southwestern Gulf of Mexico where
environmental conditions could be less hostile. If additional
southward adjustments to the track forecast are needed on
subsequent advisories, it is likely that some modest upward
adjustments to the longer-range intensity may also be required.
The initial motion estimate is northwestward or 320/11 kt. Rafael
is expected to continue to move around the southwestern side of
a mid-level ridge over the southwestern Atlantic during the next
day or so. After that time, the ridge is forecast to build
westward over the eastern Gulf of Mexico which should cause Rafael
to turn more westward over the southern Gulf of Mexico. By 72
hours, the spread in the track guidance increases once again, with
the GFS showing a more northward solution than most of the
remainder of the track guidance. The NHC track forecast has been
shifted southward once again to be in better agreement with the
various consensus aids. It is possible that future southward and
southwestward adjustment will be needed as several of the models
now show the cyclone moving west-southwestward over the southwestern
Gulf by the end of the period.
Key Messages:
1. Rafael is forecast to cross western Cuba as a major hurricane
this afternoon and evening. A hurricane warning is in effect for
this region, where a life-threatening storm surge, damaging
hurricane-force winds, and destructive waves are expected.
2. Tropical-storm-force winds, especially in gusts, are expected in
the Lower and Middle Florida Keys beginning later today and tonight.
3. Rafael will bring areas of heavy rain to the Cayman Islands and
western Cuba through Thursday. Flash flooding and mudslides are
expected in areas of higher terrain in western Cuba.
4. Rafael is forecast to meander over the south-central Gulf of
Mexico this weekend and early next week. Interests in the southern
and southwestern Gulf of Mexico should monitor the progress of this
system.
