Hurricane Gustav developed south of
Dominican Republic on August 25th from a tropical wave that
gradually got better organized as it moved across the Eastern
Caribbean Sea. Gustav, a rather small tropical cyclone
initially, quickly strengthened to a strong category one
hurricane before making landfall across Southern Haiti on August
26th with 90 mph sustained winds.
The combination of landfall and southwesterly shear weakened
Gustav to a minimal tropical storm on August 27th. Gustav
briefly re-strengthened to a strong tropical storm before going
across Jamaica on August 28th & 29th. While over Jamaica,
Gustav's circulation began to expand, with the radius of
tropical storm winds doubling during this time period.
Once Gustav emerged off the west coast of Jamaica into the
Northwestern Caribbean Sea, modest strengthening commenced,
attaining hurricane status by 4 PM on August 29th. With
excellent outflow and high oceanic heat content of the water
ahead, Gustav began to strengthen overnight, and quite rapidly
on August 30th, making landfall across Western Cuba as a 150 mph
category four hurricane.

Only weakening slightly over its passage over Cuba, Gustav emerged into the Gulf of Mexico,
and was expected to strengthen again to a strong category four
hurricane as he headed northwest towards Louisiana. Instead,
Gustav continued to slowly weaken on August 31st and the morning
of September 1st, which is still not understood why this
occurred. However, Gustav's circulation expanded a bit during
this weakening process.
Gustav made landfall near Cocodrie, Louisiana at 9:30 AM CDT
September 1st as a strong category 2 (based on 110 mph sustained
winds) and a central pressure of 955 mb. Gustav continued to
move northwest, spreading hurricane force wind gusts across
portions of Southeast and South Central Louisiana. Click the

Gustav weakened to a tropical storm and eventually a depression
as its center continued to move northwest across Central and
Northwestern Louisiana on the evening on the 1st and morning of
2nd, basically following I-49. Gustav practically stalled over
the Ark-La-Tex from the afternoon of the 2nd through the morning
hours of the 3rd. It was during this time that persistent feeder
bands caused flooding in Iberia and St. Martin parishes. Later
that evening, repetitive feeder bands, some with tornadic
thunderstorms, developed across Southwest and Central Louisiana.
One of these tornados resulted in 2 deaths near Mamou, LA early
on the 3rd. Due to thunderstorms moving over the same region for
9 to 12 hours, and the rainfall associated with the initial
passage of Gustav the day before,
radar
rainfall estimates of 15 to 25 inches occurred across
portions of Rapides, Avoyelles, Allen, Evangeline, and St.
Landry parishes.
