Hurricane Maria Discussion Number 22
NWS National Hurricane Center Miami FL AL152017
1100 AM AST Thu Sep 21 2017

Maria is maintaining a large, 40 nm wide eye, and overall, the
hurricane`s satellite presentation has not changed since the
previous advisory. An Air Force Reserve Hurricane Hunter aircraft
investigating the system has not measured flight-level winds as
high as last evening`s mission, and the central pressure has
remained relatively steady. Although there were higher SFMR winds
measured, especially to the northeast of the center, the flight
meteorologist reported that the instrument appears to be running
5-10 kt too high. Therefore, the initial intensity is held at 100

Maria appears to be moving over the remnant cold wake leftover from
Hurricane Irma, but it should begin to move over an area of higher
oceanic heat content during the next 24 hours or so. Therefore,
some strengthening is still forecast, although it is not especially
aggressive given what the latest intensity guidance is showing.
Gradual weakening is likely from 48 hours onward due to some
increase in southwesterly shear, as well as lower oceanic heat
content over the western Atlantic. Still, Maria is expected to
remain a hurricane for the next 5 days.

The initial motion is northwestward, or 310/8 kt. Maria will be
moving between a mid-level high centered south of Bermuda and a
broad trough extending from Tropical Storm Jose southwestward into
the northern Gulf of Mexico. As a result, Maria is expected to
turn gradually north-northwestward to north-northeastward by the
end of the forecast period, keeping it over the waters of the
western Atlantic after moving by the Turks and Caicos Islands and
the southeastern Bahamas. The track models continue to be tightly
clustered, and the updated NHC track forecast lies right along the
previous forecast, down the middle of the guidance envelope.


1. Flash flood emergencies continue in portions of Puerto Rico due
to persistent heavy rainfall from Maria`s trailing rainbands.
Catastrophic flooding is occurring on the island, especially in
areas of mountainous terrain, and everyone in Puerto Rico should
continue to follow advice from local officials to avoid these
life-threatening flooding conditions.

2. A Hurricane Warning is in effect for the northern coast of the
Dominican Republic, the Turks and Caicos Islands, and the
southeastern Bahamas, where Maria is expected to bring dangerous
wind, storm surge, and heavy rainfall.
