5 Hurricane
Maria made
a direct hit on the small Lesser Antilles island of Dominica
(population 72,000) near 9 pm EDT Monday, becoming Dominica’s first
Category 5 landfall on record. At the time of landfall, an Air Force
hurricane hunter aircraft measured surface winds of 160 mph and a
central pressure of 924 mb. Maria likely did catastrophic damage to
Dominica.
Heavy
rain squalls and rising winds were being observed late Monday
afternoon at Melville
Hall Airport on
Dominica, which measured sustained winds at 31 mph, gusting to 48
mph, at 6 pm EDT Monday. That station then went off-line, as
did Canefield Airport,
an hour later. A personal
weather station on the northwest end of the island stopped
transmitting as of 9:50 pm EDT Monday, after measuring a pressure of
986 mb. Satellite
loops and
radar out of Martinique andBarbados clearly
show Maria’s small, 9-mile diameter eye, surrounded by a daunting
array of spiral bands with heavy thunderstorms, Maria’s
hurricane-force winds were confined to a relatively narrow 40-mile
diameter region around the hurricane’s small eye, but the tropical
storm-force wind area was 230 miles in diameter.

Maria
put on an incredible display of rapid intensification on Monday,
going from a low-end Category 1 storm with 75 mph winds and a
pressure of 982 mb at 0Z Monday, to a Category 5 storm with 160 mph
winds and a 925 mb pressure 24 hours later. There have now been two
Atlantic Category 5 storms in 2017: Maria and Irma. The Atlantic has
had only five other years on record with multiple Cat 5s: Dean and
Felix in 2007; Emily, Katrina, Rita and Wilma in 2005; Carla and
Hattie in 1961; and two Cat 5s each in 1932 and 1933.
Dominica hurricane history
Dominica
(not to be confused with the Dominican Republic on the island of
Hispaniola) has received numerous strikes by tropical storms over the
years, but only five direct hits from hurricanes since records began
in 1851. This is, in part, because Dominica is a small island, but
also because it is uncommon for water temperatures to be warm enough
to the east of the island to allow intensification of westward-moving
tropical storms into hurricanes before reaching Dominica.
The
only major hurricane to hit Dominica was Category 4 Hurricane David
of 1979. David killed 40 people and did $160 million in damage (2017
dollars). The most expensive storm to hit Dominica was Tropical
Storm Erika of
August 2015. Erika caused extensive flooding and landslides across
the island, killing 30 and causing $500 million in damage (2017
dollars). This was a disastrous 90% of their yearly GDP. Erika’s
name was retired from the list of Atlantic storms due to its impact
on Dominica, making it one of only two Atlantic tropical storms,
along with Tropical Storm Allison of 2001, to have their names
retired.
Beside
David, four other hurricanes have hit the island: Category 1 Marilyn
of 1995, and Category 1 hurricanes in 1930, 1916, and 1915.
We’ll
have a full update on Maria and Jose on Tuesday.
