[edit] Summary

Radar image of Hurricane Wilma as it slowly drifted inland over the NE Yucatan Peninsula. At the time Wilma was a strong Category 4 hurricane with winds near 140 mph.

Notice the two rings of maximum signature. An onset of eye wall replacement cycle is evident here. The inner eye wall would be disrupted by land interaction but it regenerated over the "Loop Current" and the new eye would not clear until moments before landfalling on Florida. The second eye wall may explain why Wilma retained much of its strength despite land interaction (besides retaining 75% of its circulations over water).

[edit] Licensing

Okay, this is somewhat complicated to rationalise. While the image is indeed originally produced by the Mexican Weather Service (and the Mexican government does not release its works into the public domain), the fact that it has been released and distributed by the US National Oceanic and Atmospheric Administration should allow us to use it here. The {{PD-USGov-NOAA}} is not entirely accurate but is the best I can find.

Article	Meteorological history of Hurricane Wilma
Portion used	All; image was freely available and reproduced in public domain documents ({{PD-USGov-NOAA}}), so no damage is possible to the negligible commercial value of the image.
Low resolution?	No; reducing the size of the image has the potential of distorting radar returns near the center of the image, which are the important part of the image; these returns are in cases only a few pixels wide.
Purpose of use	Shows the organization and strength of Hurricane Wilma during its landfall near Cozumel.
Replaceable?	There are no free alternatives available, nor any can be produced, as this was a one-time event.
