What's key is that meteorologists don't stick to a single line or track because a slight change can mean a big difference, Mayfield said.For example, a tiny turn over Cuba, where mountains can eat up storms, can weaken Irma considerably.

WASHINGTON -- The fate of Florida depends on when and how Hurricane Irma makes a right turn.

National Weather Service Director Louis Uccellini says forecasters have no doubt it will turn in the days ahead.

Pool Trac Management Justin and John We have completed the second Stage of our updates. Starting Tomorrow we will be releasing new updates to the Management Site and Apps.

Most of today's updates are all backend database updates in preperation for the following stages. We have decided to release the updates in groups instead of all at once.

A look at how those predictions are made: The place to start is the National Hurricane Center's official forecast, say several meteorologists who are not part of the federal government.

"You can't beat the hurricane center forecast," said Miami television meteorologist Max Mayfield, who was the director of the hurricane center from 2000 to 2007.

If you have any questions or concerns, please contact Pool Trac Support. We've added a new flyout menu that is accessed via the new "Menu" button in the upper left corner.

We've also added a new Help and Search function on every screen. First, our old menu system was outdated and took up a lot of room on the screen.

Below is a link to a quick tutorial of the new menu system.
