March 17-18, Early Post
March 18, 2007Brrrrr! The cold front has swept across Cuba. Winds in Havana are north at 15-18 MPH. These conditions should stop all migration. I may not even get up in the middle of the night to check the radar!
Current weather models indicate conditions adverse to migration through the middle of the next week.
March 16-17
March 17, 2007At this time (c. 03:00 UTC) there are no radar detectable migrants outbound from Cuba. There a numerous showers/thunderstorms over the Cuban coast and Straits. Also, after several nights of good migration, the supply of migration ready birds might have been exhausted.
March 15-16
March 16, 2007There were scattered showers and thunderstorms along the Cuban coast during the take-off time that may have reduced tonight’s flight. Even so, some birds were on the move. An image from c. 04:00 UTC shows birds approaching the Keys. This image will roll off he archive in four days.
March 13-14
March 14, 2007Another good migration tonight (linked image is from c. 03:00 UTC). The image shows the bulk of the migrating birds just north of Cuba. The image will roll-off the archive in four days.

March 13, 2007Further review has shown the largest flight so far for this season. It even warranted an animation…
March 12-13
March 13, 2007There is a pretty good flight tonight (see above link of image from c. 02:00 UTC). Also several chaff trails running west to east, over and south of the Keys. As usual, the linked image will roll-off in four days.
March 11-12
March 12, 2007Winds over Cuba have shifted back to northerly. There is no detectable migration tonight.
