1100 AM EDT Thu Aug 21 2025

Erin remains a sprawling hurricane, with its tropical-storm-force
winds extending nearly 500 n mi across. In fact, comparing Erin with
systems around the same intensity and in similar locations over the
past couple of decades indicates that it is around the 90th
percentile in size. The Air Force Hurricane Hunters indicate that
the peak winds have come down a bit, and based on their data, the
initial intensity is set at 85 kt. Although the core of Erin is
pulling away from the United States, coastal flooding and
tropical-storm-force winds continue along portions of the North
Carolina and Virginia coasts. The center of Erin passed just east of
NOAA buoy 41001 earlier this morning, and it reported a minimum
pressure of 962 mb and a maximum significant wave height of 45 ft.
The associated swells are covering nearly the entire western
Atlantic from the Bahamas to Atlantic Canada.

Erin is moving north-northeastward at 16 kt. A turn to the northeast
or east-northeast with a significant increase in forward speed
within the mid-latitude westerlies is expected to begin tonight,
taking Erin out to sea over the north Atlantic during the next
several days. The models are in good agreement, and only minor
changes were made to the previous NHC forecast.

Increasing southwesterly vertical wind shear, drier mid-level air,
and cooler SSTs should cause Erin to gradually lose strength over
the next several days. Extratropical transition is now expected to
be complete by early Saturday, when the system is forecast to
develop fronts after it crosses the north wall of the Gulf Stream.
The NHC intensity forecast follows HCCA and IVCN in the short term,
but leans toward the global model guidance during the predicted
extratropical phase.

KEY MESSAGES:

1. Erin will continue to produce life-threatening surf and rip
currents along the beaches of the Bahamas, much of the east coast of
the U.S., Bermuda, and Atlantic Canada during the next several days.
Beachgoers in those areas should follow advice from lifeguards,
local authorities, and beach warning flags.

2. Storm surge flooding and tropical storm conditions will continue
on the North Carolina Outer Banks today. The storm surge will be
accompanied by large waves, leading to significant beach erosion and
overwash, making some roads impassible.

3. Tropical storm conditions are expected today along the Virginia
coast. Wind gusts to tropical storm force are likely along
portions of the remainder of the U.S. Mid-Atlantic and southern New
England coasts today through early Friday.

4. Tropical storm conditions are possible on Bermuda this afternoon
through early Friday. Gusts to gale force are possible along the
coast of Nova Scotia on Friday and the Avalon Peninsula of
Newfoundland on Saturday.

500 PM AST Thu Aug 21 2025

Erin is gradually pulling away from the U.S., but coastal flooding
and tropical storm conditions continue across portions of the North
Carolina and Virginia coastline. A pair of ASCAT passes from a few
hours ago confirmed Erin's large size with its associated
tropical-storm-force winds extending nearly 500 n mi across. In
fact, comparing Erin with other systems around the same intensity
and in similar locations over the past couple of decades indicates
that it is around the 90th percentile in size. Overall, the
structure of the system has changed little since the aircraft
departed earlier today, and based on that data and the satellite
intensity estimates, the initial intensity is held at 85 kt. Erin is
producing very rough seas, and the associated swells are covering
nearly the entire western Atlantic from the Bahamas to Atlantic
Canada.

Erin has turned northeastward, and it is currently moving at 050/17
kt. A faster motion to the northeast or east-northeast is expected
within the mid-latitude westerlies over the next few days, taking
Erin out to sea over the north Atlantic. The models are in good
agreement, and only minor changes were made to the previous NHC
forecast.

The environmental conditions are expected to become increasingly
hostile around Erin, as southwesterly vertical wind shear is likely
to steadily increase while humidity values and sea surface
temperatures decrease. This should result in weakening, but Erin
will likely only slowly lose strength due to its large size. Erin
is expected to cross the north wall of the Gulf Stream in a couple
of days, and that should help lead to its extratropical transition.
The NHC intensity forecast is similar to the previous one, and
follows HCCA and IVCN in the short term, but leans toward the global
model guidance during the predicted extratropical phase.

KEY MESSAGES:

1. Erin will continue to produce life-threatening surf and rip
currents along the beaches of the Bahamas, much of the east coast of

2. Storm surge flooding will continue on the North Carolina Outer
Banks through tonight. The storm surge will be accompanied by large
waves, leading to significant beach erosion and overwash, making
some roads impassible.

3. Tropical storm conditions are expected for a few more hours
along portions of the northeast North Carolina and Virginia coast.
Wind gusts to tropical storm force are likely along portions of the
remainder of the U.S. Mid-Atlantic and southern New England coasts
today through early Friday.

4. Tropical storm conditions are expected on Bermuda this
evening through early Friday. Gusts to gale force are possible
along the coast of Nova Scotia on Friday and the Avalon Peninsula of
Newfoundland on Saturday.

Hurricane Erin Discussion Number 43
NWS National Hurricane Center Miami FL AL052025
1100 PM AST Thu Aug 21 2025

Erin has changed little in organization during the past several
hours. An area of convection seen near the center in conventional
satellite imagery is associated with a fragment of an inner eyewall
seen in microwave imagery, and outer convective bands continue in
association with the outer wind maximum seen in scatterometer data.
Satellite intensity estimates are in the 75-85 kt range and have
not changed much since the last advisory, and based on this the
initial intensity remains 85 kt. Erin continues to have a very
large area of tropical-storm force winds, and comparing Erin with
other systems around the same intensity and in similar locations
over the past couple of decades indicates that it is around the
90th percentile in size. The cyclone also continues to produce a
very large area of high seas covering nearly the entire western
Atlantic from the Bahamas to Atlantic Canada.

The hurricane is now moving east-northeastward or 065/19 kt. A
faster motion toward the east-northeast is expected within the
mid-latitude westerlies over the next 2-3 days, taking Erin out to
sea over the north Atlantic. Some decrease in forward speed is
expected by 120 h. The track models are tightly clustered, and the
new forecast track has only minor adjustments from the previous
track.

Erin is moving into an area of increasing shear and toward cooler
sea surface temperatures, and the cyclone is expected to merge with
a front and become extratropical in about 36 h. However, global
models forecast that the cyclone will only gradually weaken as it
moves across the north Atlantic. The new intensity forecast is
similar to the previous forecast and is based mainly on a blend of
the GFS and ECMWF surface winds forecasts.


KEY MESSAGES:

1. Erin will continue to produce life-threatening surf and rip
currents along the beaches of the Bahamas, much of the east coast of
the U.S., Bermuda, and Atlantic Canada during the next several days.
Beachgoers in those areas should follow advice from lifeguards,
local authorities, and beach warning flags.

2. Storm surge flooding should subside on the North Carolina Outer
Banks tonight. While this happens, the storm surge will continue to
be accompanied by large waves, leading to significant beach erosion
and overwash, making some roads impassible.

3. Wind gusts to tropical storm force are likely along portions of
the U.S. Mid-Atlantic and southern New England coasts through early
Friday.

4. Tropical storm conditions are expected on Bermuda through early
Friday. Gusts to gale force are possible along the coast of Nova
Scotia on Friday and the Avalon Peninsula of Newfoundland on
Saturday.

Hurricane Erin Discussion Number 44
NWS National Hurricane Center Miami FL AL052025
500 AM AST Fri Aug 22 2025

Erin has begun extratropical transition. The center is now exposed
to the southwest of the remaining central deep convection due to
30-35 kt of southwesterly shear. In addition, the hurricane has
developed an expansive cirrus shield to the north, and stratus and
stratocumulus clouds off the Mid-Atlantic U.S. coast suggest that
cold air advection is occuring in the hurricane's wake. Based on
the degradation of the satellite presentation since the previous
full advisory, the initial intensity is lowered to 80 kt. The wind
field continues to grow, and tropical-storm-force winds now extend
as far as 320 n mi from the center.

The hurricane has been moving northeastward, or 055/19 kt. Erin
will accelerate toward the east-northeast, embedded within the
mid-latitude westerlies, reaching a peak speed of about 35 kt in 48
hours. A significant reduction in forward speed is then expected
on days 3 through 5 as the cyclone becomes cut off from the
westerlies, stalling or meandering just south of Iceland by the
middle of next week. The NHC track forecast is close to a blend of
the GFS, ECMWF, and HCCA models, and no significant changes were
made from the previous forecast.

Global model thermal fields, model-simulated satellite imagery, and
phase-space diagrams indicate that Erin should become post-tropical
by 24 hours. The NHC intensity forecast generally follows a blend
of the GFS and ECMWF surface wind fields, showing only some
weakening during the next 36-48 hours. Global models are in good
agreement that the post-tropical cyclone will phase with an
upper-level trough in 48-60 hours, inducing baroclinic
reintensification and possibly the development of a sting jet on
the back side of the low. The NHC official forecast shows that
strengthening at 60 hours. Steady weakening, and even more
broadening of the wind field, should occur on days 3 through 5 as
the low becomes vertically stacked south of Iceland.


KEY MESSAGES:

1. Erin will continue to produce life-threatening surf and rip
currents along the beaches of the Bahamas, much of the east coast of
the U.S., Bermuda, and Atlantic Canada during the next several days.
Beachgoers in those areas should follow advice from lifeguards,
local authorities, and beach warning flags.

2. Coastal flooding is expected at times of high tide along portions
of the U.S. Mid-Atlantic and New England coasts through tonight,
making some roads impassable. Large waves along the coast could
also cause significant beach erosion and overwash.

3. Gusts to gale force are possible along the coast of Nova Scotia
today and the Avalon Peninsula of Newfoundland on Saturday.

NWS National Hurricane Center Miami FL AL052025
1100 AM AST Fri Aug 22 2025

Erin is now well into its extratropical transition. While there is
some convection that has recently reformed near the center, all of
its other convection has shifted on the left side, with noticeable
frontal features in the northeastern quadrant. Additionally, the
stratus and stratocumulus clouds off the Mid-Atlantic U.S. coast
continue to suggest that cold air advection is occuring in the
hurricane's wake. The initial intensity is kept at 80 kt pending
receipt of the full late-morning scatterometer data, though the
partial pass suggested Erin had grown even larger.

The hurricane is moving faster to the east-northeast, now estimated
at 24 kt. Model guidance is rapidly accelerating Erin in that
direction over the weekend, reaching a peak speed of up to 40 kt
Sunday. The powerful extratropical low should slow down and could
undergo a loop over the far North Atlantic early next week as it
becomes a large occluded low. The new forecast is a bit faster and
south of the previous one, based on the latest corrected consensus
guidance from HCCA and Google Deep Mind.

Current trends and model fields indicate that Erin should complete
extratropical transition by tonight, with perhaps a slight weakening
of the winds on Saturday. However, Erin is forecast to become an
even larger and stronger system late Saturday into Sunday due to
phasing with a mid-latitude trough, inducing baroclinic
reintensification and even the development of a sting jet on the
back side. While they disagree on the exact timing, the global
models are all showing a 75-90 kt sting jet on Sunday. The new NHC
forecast is raised during the extratropical phase for Sunday, and
still could be too low if the latest ECMWF solution is correct. A
steady weakening is likely to occur early next week as Erin occludes
and loses its upper support south of Iceland.


KEY MESSAGES:

1. Erin will continue to produce life-threatening surf and rip
currents along the beaches of the Bahamas, much of the east coast of
the U.S., Bermuda, and Atlantic Canada during the next several days.
Beachgoers in those areas should follow advice from lifeguards,
local authorities, and beach warning flags.

2. Coastal flooding is expected at times of high tide along portions

making some roads impassable. Large waves along the coast could
also cause significant beach erosion and overwash.

today and the Avalon Peninsula of Newfoundland on Saturday.

NWS National Hurricane Center Miami FL AL052025
500 PM AST Fri Aug 22 2025

Erin has now become a powerful extratropical low. While there is
still deep convection near the center, scatterometer data clearly
shows that Erin has become frontal. Thus, extratropical transition
has been completed, and this is the last NHC advisory. The initial
intensity remains 80 kt based on the multiple earlier scatterometer
winds near 70 kt, with very large gale- and storm-force wind-radii
noted.

While the general track and intensity forecast is about the same as
before, one specific marine hazard to highlight is the consistent
development of a strong sting jet in the southern semicircle of Erin
by Sunday, as well as a very large hurricane-force wind field.
Model guidance now suggest that a maximum of 80-90 kt is possible,
and the NHC intensity forecast is raised to 85 kt then. No other
noteworthy changes were made to the previous forecast.

Additional information on this system can be found in High Seas
Forecasts issued by the National Weather Service, under AWIPS
