A tropical disturbance (95L) has formed near 11N, 79W, just north of Panama, in the extreme southern Caribbean. This disturbance has a large but disorganized area of heavy thunderstorm activity associated with it. The latest QuikSCAT satellite imagery from 5:45am EST today caught just the east side of the disturbance, and revealed top winds of 35-40 mph. An ill-defined and elongated surface circulation was apparent in the QuikSCAT data, and some evidence of rotation can be seen on the latest visible satellite loop of the region.


Figure 1. preliminary model tracks for the Panama disturbance, 95L.

Wind shear is around 10 knots over the disturbance, which is low enough to allow some slow development over the next two days. It is possible a tropical depression could form by Sunday, as wind shear is expected to remain low over the extreme southern Caribbean. Steering currents are weak, but a slow westward motion beginning on Saturday is indicated by most of the models. The system appears to be a threat primarily to Nicaragua, Costa Rica, Honduras, and Panama. Any northward movement of the storm would bring it into a area of high wind shear that would quickly tear it apart.

I'll be back Saturday morning with an update.

Someone fed the 00Z 95L GFDL run some steroids...maxs out at 105kts before landfall!

No Quikscat passes this morning, not 95L, C Atlatic blob or the invest in the S Atlantic.

95L has become strong enough for a dvorak reading...

Michael, direction looks good, intensity overdone. Could cross into the Pacific intact. That is very possible.

good morning all

95L is looking a little ragged this morning.
Although the models still call for a W drift that is not what normally prevails this time of year. In fact it looks to me like the system has already drifted N to near 12 degrees.
