Return of TC summaries

   Here is the revised format for the TC summaries. Clicking an image will bring up large version and allow one to scroll through the different images in the post. This is useful when comparing multiple images of the same storm.
   New to this version are pairs of images depicting the wind field around each storm. These were created from a computer model developed at Colorado State University and is called Multiplatform Tropical Cyclone Surface Winds Analysis (MTCSWA). The image on the right is simply a zoomed in version of the left image. At the bottom of these is some data  on the storm, such as the maximum winds depicted (VMAX), how far from the center these winds are found (RMW), and how far out the winds go in each quadrant.


LESLIE

NHC Forecast
Remarks: Leslie is a storm that has had, and will continue to have, a hard life. It is currently struggling against moderate shear and the forecast calls for the shear to increase further. This is hindering development, yet it is still forecasted to reach hurricane strength eventually.

Remarks: Kirk is accelerating quickly as it interacts with the mid-latitude westerlies. The shear that will cause, and low sea surface temperatures will cause the storm to loose its tropical characteristics.
 
 


ILEANA

Remarks: ILEANA is pretty much gone, the visible imagery depicts a storm with very little convection remaining. Plus, that field of  small cumulus clouds wrapping around the storm indicates it is moving into a stable environment.
