Paloma is now a “high-end” category 1 hurricane and continues to strengthen.  The greatest concerns throughout the Caymans are high winds – storm surge concerns are not as pressing.  Jamaica is expected to get only fringe winds.  Paloma is expected to continue toward the northeast, travel across Cuba and into the Bahamas.

Those of you who have studied the circulation of air with tropical cyclonic systems can probably “see” in the satellite image above both inflow and outflow cloud patterns.  For those who are not familiar with the difference between the two I am including an image below of hurricane Ike on September 9, 2008.  He is centered just offshore of northwest Cuba.  I have drawn air flow arrows to show the cyclonic inflow (red) and the flow that occurs aloft, anticyclonic outflow (blue).

Inflow consists of the harder-edged clouds with sharp contrast – Outflow consists of the more diffuse cirrus and cirrostratus of the upper layer.
