Re: Igor Strengthening and 92L

Good evening...Igor finally has gotten his wings and is on the move west. We have about a 5 day window before we're going to know whether recurvature lies in Igor's future.

For the moment the models beyond 5 days have Igor approaching a COL between two ridges and a shortwave to the north at 30.0N and 73.0W. Igor will slow and spend a few days in this vicinity if the models verify and has a future date being caught up in the westerlies.

There is model difference as expected in the longer ranges and all are focused on the strength of the subtropical ridge in the Atlantic.

Turning to the wave in the Caribbean; the models take this feature west and emerge it over the Pacific in five days.

I'm aware there is a wave expected to develop and trail Igor but it's way too early to speculate since this wave is over Africa as of this typing.
