Re: Things to Watch

The winds at the San Juan NWS radar have begun to back over the last hour. From SSE to NNE at 0044Z.
This may or may not be indicative of the outer edges of the wave reaching the radar site. Wind speeds are up to 10knots at the 3000ft level. ( The radar site is located in mountainous terrain.)

Just something to watch...

Satellite imagery indicates the center of the wave is located SSE of St Croix, USVI. Using cirrus directional changes and lightning data in the NE through SSE areas of the wave. Appears to be moving NW at 10-15 knots. The system is very large. Covering the area from 60-70W.
