Hurricane Maria Discussion Number 12
NWS National Hurricane Center Miami FL AL152017
1100 PM AST Mon Sep 18 2017
KEY MESSAGES:
1. Maria will affect portions of the Leeward Islands and the British
and U.S. Virgin Islands as an extremely dangerous major hurricane
during the next couple of days, and hurricane warnings are in effect
for many of these islands.
2. Maria is likely to affect Puerto Rico as an extremely dangerous
major hurricane, and a hurricane warning is in effect for that
island. Preparations to protect life and property should be rushed
to completion.
3. The potential for a life-threatening storm surge, accompanied by
large and destructive waves, has increased for the Leeward Islands,
the Virgin Islands, and Puerto Rico.
4. Life-threatening flash floods and mudslides from heavy rainfall
are expected across the Leeward Islands, including Puerto Rico and
the U.S. and British Virgin Islands.
Category 5 Hurricane Maria is moving across the northeast
Caribbean waters and is expected to reach southeastern Puerto Rico
this morning. The eye of Maria then will cross Puerto Rico during
the day, and pass just north of the northeast coast of the
Dominican Republic Wednesday night and Thursday. See the special
features section for further details. Low level wind convergence
east of a tropical wave in the western Caribbean is producing a
large area of scattered showers and isolated tstms in the SW
Caribbean from S of 15N W of 77W. Expect the wave to continue
moving west with convection mainly east-southeast of the wave
axis. Scatterometer data shows mainly light to gentle trade winds
west of 71W, with the remainder of the basin N of 15N experiencing
cyclonic winds associated with Hurricane Maria. Fresh to locally
strong winds are off the Nicaragua coast associated with the
aforementioned convection.
