IKE
140 MPH Cat. 4 hurricane is about 475 miles northeast of the northern most Leeward Islands moving west-
northwest (290 deg) near 16 MPH. Ike rapidly intensified under ideal environmental conditions that lasted about
24 hrs…..but since has peaked during the night and is beginning to slowly weaken because of some fairly strong
northerly wind shear. The shear is modeled to inhibit Ike for the next few days…..then is expected to weaken
about the time the hurricane is approaching the Turks Cacaos Islands Sunday. Ike will probably weaken to a
lower end Cat. 3 or thereabouts and stabilize. The synoptic pattern is evolving as expected with a deep layer
Mid Atlantic ridge north of Ike waiting to build westward behind Hanna…..as Hanna rapidly lifts out to the north
and then northeast the next three days. This will force Ike west or possibly west-southwest towards the Turks
Cacaos and Southern Bahama Islands. The NEW European model that updated a short time ago shows a stronger
Western Atlantic ridge…..and has shifted its Ike projections about 150-200 miles south to near Havana Monday
evening…..then forecasting a northwest forward motion into the Central GOM . This is a dramatic change from
the last several runs of the model…..a model that has to be taken seriously considering it’s relatively low past
verification errors. Hanna has stirred the water up in the Bahamas and Turks causing some upwelling of slightly
cooler water to the surface. This should lower the heat content of the water available for Ike somewhat limiting
potential strengthening beyond Cat 3 in that area. Confidence is moderate to high that the Bahamas will be
significantly impacted. Some of the reliable normally left side bias guidance model beyond five days show a
Southeast / East Coast US impact…..while other normally right side bias models have Ike recurving to the
northeast without a US landfall. Also very long term climatology supports a recurving storm in the Atlantic…..
albeit close in to the US. Bottom Line is….. it’s too early to tell with a high degree of confidence if Ike will severely
impact the Southeast United States or GOM. It will likely be Monday or Tuesday before that question can be
answered. For the record…..I still favor Ike as an Atlantic side hurricane vs a GOM storm…..but my confidence has
been lowered by the latest ECMFW run.
