SUMMARY OF 1100 AM AST...1500 UTC...INFORMATION
-----------------------------------------------
LOCATION...25.9N 44.4W
ABOUT 1315 MI...2115 KM SW OF THE AZORES
MAXIMUM SUSTAINED WINDS...145 MPH...230 KM/H
PRESENT MOVEMENT...NNE OR 15 DEGREES AT 10 MPH...17 KM/H
MINIMUM CENTRAL PRESSURE...938 MB...27.70 INCHES


WATCHES AND WARNINGS
--------------------
There are no coastal watches or warnings in effect.

Interests in the Azores should monitor the progress of Lorenzo.
Watches could be issued for those islands later today or tonight.


DISCUSSION AND OUTLOOK
----------------------
At 1100 AM AST (1500 UTC), the center of Hurricane Lorenzo was
located near latitude 25.9 North, longitude 44.4 West. Lorenzo is
moving toward the north-northeast near 10 mph (17 km/h) and this
motion is expected to continue through tonight. A turn to the
northeast along with an increase in forward speed should occur on
Monday and continue through Wednesday.

Maximum sustained winds are near 145 mph (230 km/h) with higher
gusts.  Lorenzo is a category 4 hurricane on the Saffir-Simpson
Hurricane Wind Scale.  Steady weakening is expected over the next
few days, but Lorenzo is still expected to be a potent hurricane in
a couple of days.

Lorenzo is a large hurricane, with hurricane-force winds extending
outward up to 80 miles (130 km) from the center and
tropical-storm-force winds extending outward up to 275 miles (445
km).

The estimated minimum central pressure is 938 mb (27.70 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL:  Lorenzo is expected to produce total rain accumulations
of 3 to 6 inches over much of the western Azores and 1 to 2 inches
over the central Azores Tuesday and Wednesday.  This rainfall could
cause life-threatening flash flooding in the western Azores.

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.  Please consult
products from your local weather office.

hurricane as is approaches the Azores in a few days.

Hurricane-force winds extend outward up to 50 miles (85 km) from the
center and tropical-storm-force winds extend outward up to 275 miles
(445 km).

The estimated minimum central pressure is 925 mb (27.32 inches).


HAZARDS AFFECTING LAND

northeastern coast of South America and the Lesser Antilles and are
expected to spread westward to portions of the north coasts of the
Greater Antilles, the Bahamas, Bermuda, and the east coast of the
United States during the next few days.  Swells are also expected
to build near the Azores on Sunday and Monday.  These swells are
likely to cause life-threatening surf and rip current conditions.

Waving goodbye to Sept 2019 this afternoon. Onward to Oct 2019 and hopefully some cooler weather and no late season tropical mischief for the NW GOM. A peaceful satellite image this afternoon.
