Re: 97L

I'm checking the San Juan radar storm velocity product. It appears that a vortice is just offshore of the northern coast of Puerto Rico. Middle of the island and about 20-40 miles north. I'll attach a photo as soon as I get it resized.

NW quadrant of the radar where blue and gold meet. In this location for a two hour duration. Mileage rings place the vortice about 45 miles offshore. This is elevated as the San Juan radar site is in or near the mountains near 3000 feet.. That would place the observed vortice around 4000 to 5000 feet using 0.5 elevation on the radar.



This is the composite reflectivity image at the same time. Convection is co-located with the observed vortice. My opinion only.
