DISCUSSION AND OUTLOOK
----------------------
At 200 PM AST (1800 UTC), the center of Hurricane Lorenzo was
located near latitude 36.0 North, longitude 36.8 West. Lorenzo is
moving toward the northeast near 25 mph (41 km/h). The hurricane
should move in the same general direction but at a faster forward
speed during the next couple of days. On the forecast track, the
center of Lorenzo is expected to pass near the western Azores early
Wednesday.
Maximum sustained winds are near 100 mph (155 km/h) with higher
gusts. Only slow weakening is expected during the next 48 hours.
Hurricane-force winds extend outward up to 90 miles (150 km) from
the center and tropical-storm-force winds extend outward up to 345
miles (555 km).
The estimated minimum central pressure is 962 mb (28.41 inches).
HAZARDS AFFECTING LAND
----------------------
Key messages for Lorenzo can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC
and on the web at www.hurricanes.gov/text/MIATCDAT3.shtml
WIND: Hurricane conditions are expected within the hurricane
warning area early Wednesday morning, with tropical storm conditions
beginning tonight. Tropical storm conditions are expected in
the tropical storm warning area by early Wednesday.
RAINFALL: Lorenzo is expected to produce total rain accumulations
of 1 to 2 inches (25 to 50 mm) over the western Azores and up to 1
inch (25 mm) over the central Azores Tuesday and Wednesday.
SURF: Swells generated by Lorenzo have spread across much of the
North Atlantic basin, and are affecting the east coast of the United
States, Atlantic Canada, the Bahamas, portions of the Greater and
Lesser Antilles, the Azores, and portions of the coast of Europe.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 PM EDT Tue Oct 1 2019
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
The National Hurricane Center is issuing advisories on Hurricane
Lorenzo, located several hundred miles southwest of the western
Azores.
A broad area of low pressure located over the northwestern Caribbean
Sea continues to produce disorganized showers and thunderstorms. Any
development of this system is expected to be slow to occur while it
moves to the west-northwest near the Yucatan peninsula in a couple
of days, and over the southern Gulf of Mexico by Friday.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.
Disorganized cloudiness and showers that extend from the
southeastern Bahamas northeastward across the western Atlantic for
several hundred miles are associated with a surface trough.
Development of this system, if any, is expected to be slow to occur
while it moves to the northeast at 5 to 10 mph, well south and east
of Bermuda.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.

Hurricane Lorenzo Discussion Number 37
NWS National Hurricane Center Miami FL AL132019
1100 AM AST Tue Oct 01 2019
Lorenzo remains a well organized hurricane this morning as it heads
toward the Azores. The eye has made a reappearance in infrared
satellite imagery, and the cloud tops associated with the
surrounding ring of convection have cooled. The advisory intensity
remains 85 kt, which is the consensus of the latest objective
and subjective satellite intensity estimates that range from 77 to
90 kt. Lorenzo is expected to maintain its intensity today, but it
will be moving over progressively colder waters and into an area of
increasing shear, which should cause gradual weakening by
Wednesday. The global models show the hurricane merging with a
frontal zone, and becoming extratropical in about 36 hours. The
extratropical low should weaken in a couple of days while it moves
near Ireland and Great Britain, and then it is forecast to dissipate
over Europe by 96 hours.
Lorenzo is moving northeastward at 22 kt. The hurricane should
continue to accelerate northeastward ahead of a mid-latitude trough
over the central Atlantic during the next day or two. After that
time, the cyclone is predicted to decelerate and turn
east-northeastward or eastward within the low-level westerly flow.
The global model guidance is in excellent agreement through the
first 36-48 hours, and has also come into somewhat better agreement
on the eastward turn later in the period. The updated NHC track has
been adjusted southeastward at 72 hours, but still lies north of the
multi-model consensus. An additional southward and eastward
adjustment of the post-tropical cyclone's track near Ireland
and the United Kingdom may be necessary in future advisories.
Lorenzo is producing huge seas over the north Atlantic. Full
information on the High Seas Forecasts can be found at the Ocean
Prediction Center under AWIPS header NFDHSFAT1, WMO header FZNT01
KWBC, and online at ocean.weather.gov/shtml/NFDHSFAT1.php.

by under WMO header FQNT21 EGRR and on the web at

Key Messages:
1. Lorenzo is expected to bring hurricane and tropical storm force
winds to the Azores beginning tonight, and these conditions
will continue into Wednesday. Hurricane and Tropical Storm Warnings
are in effect for the Azores.
2. Swells generated by Lorenzo have spread across much of the
North Atlantic, and are affecting the east coast of the United
States, Atlantic Canada, the Bahamas, portions of the Greater and
Lesser Antilles, and portions the coast of Europe. These swells
will produce life-threatening surf and rip currents.

DISCUSSION AND OUTLOOK
----------------------
At 200 AM AST (0600 UTC), the center of Hurricane Lorenzo was
located near latitude 32.8 North, longitude 40.5 West. Lorenzo is
moving toward the northeast near 22 mph (35 km/h). The hurricane
should move in the same general direction but at a faster forward
speed during the next few days. On the forecast track, the center
of Lorenzo is expected to pass near the western Azores early on
Wednesday.
Maximum sustained winds remain near 105 mph (165 km/h) with higher
gusts. Only slight weakening is anticipated before Lorenzo moves
near the Azores, with faster weakening expected on Thursday.
Lorenzo is a very large tropical cyclone. Hurricane-force winds
extend outward up to 105 miles (165 km) from the center and
tropical-storm-force winds extend outward up to 345 miles (555 km).
The estimated minimum central pressure is 956 mb (28.23 inches).

WIND: Hurricane conditions are expected within the hurricane
warning area early Wednesday morning, with tropical storm conditions
beginning tonight. Tropical storm conditions are expected in
the tropical storm warning area by early Wednesday.
RAINFALL: Lorenzo is expected to produce total rain accumulations
of 1 to 3 inches (25 to 75 mm) over the western Azores and up to 1
inch (25 mm) over the central Azores today and Wednesday.
SURF: Swells generated by Lorenzo are spreading across much of the
North Atlantic basin. These swells are likely to cause life-
threatening surf and rip current conditions, especially across the
Azores. Please consult products from your local weather office.

Hurricane Lorenzo Discussion Number 35
NWS National Hurricane Center Miami FL AL132019
1100 PM AST Mon Sep 30 2019
Lorenzo has not changed appreciably during the past several hours
on satellite imagery, with an eye still present along with a large
cloud shield in the northeastern quadrant. Dvorak estimates remain
near 90 kt so that will be the initial wind speed. The initial
wind field has also grown according to the latest scatterometer
data, and that is reflected in the wind radii analyses.
The hurricane is now moving faster and has turned northeastward at
about 17 kt. Lorenzo should continue to accelerate to the northeast
during the next couple of days ahead of a large mid- latitude
trough, and the model guidance remains in tight agreement taking the
hurricane near the western Azores. The longer-range future of
Lorenzo is a little clearer tonight as the global models are in much
better agreement on the cyclone turning east- northeastward close to
Ireland and then eastward across Great Britain, dissipating over
western Europe by 96 h. The new forecast is shifted southward, and
is close to a blend of the latest UKMET/ECMWF and GFS solutions.
Lorenzo is forecast to slowly weaken tomorrow due to the cyclone
moving over progressively cooler waters. Extratropical transition
should occur by 48 hours, and there is unanimous global model
agreement on Lorenzo keeping much of its strength through that time.
Weakening is then anticipated while the low approaches Ireland and
the U.K., although the wind speed forecast at 72 hours is
deceptively low since the radius of maximum winds is possibly
already onshore.
It is also worth mentioning that there will be some enormous seas on
the eastern side of Lorenzo. The hurricane will be accelerating to
the northeast in the same general direction for a couple of days.
Combined with the large size and intensity, this is a recipe for an
amplified wave field on the eastern side due to a phenomenon called
trapped-wave fetch. Full information on the High Seas Forecasts can
be found at the Ocean Prediction Center under AWIPS header
NFDHSFAT1, WMO header FZNT01 KWBC, and online at
ocean.weather.gov/shtml/NFDHSFAT1.php.

by under WMO header FQNT21 EGRR and on the web at

Key Messages:
1. Lorenzo is expected to bring hurricane and tropical storm force
winds to the Azores beginning Tuesday night, and these conditions
will continue into Wednesday. Hurricane and Tropical Storm Warnings
are in effect for the Azores.
2. Large swells generated by Lorenzo will continue to spread across
much of the north Atlantic basin during the next few days. These
swells will produce life-threatening surf and rip currents,
especially across the Azores.

speed tonight through Wednesday. On the forecast track, the center
of Lorenzo is expected to pass near the western Azores early on
Wednesday.
Maximum sustained winds are near 105 mph (165 km/h) with higher
gusts. Some fluctuations in intensity are possible tonight. A
weakening trend is expected to resume on Tuesday.
Lorenzo is a very large hurricane, with hurricane-force winds
extending outward up to 90 miles (150 km) from the center and
tropical-storm-force winds extending outward up to 310 miles (500
km).
The estimated minimum central pressure is 957 mb (28.26 inches).
