As some hurricane forecasters predicted, October is proving to be an active month for the 2008 Atlantic hurricane season. As one tropical storm (Nana) fades away in the Atlantic, another (Omar) has formed today in the eastern Caribbean. And yet another tropical depression - the 16th of the season - is taking shape in the western Caribbean.

First, remnants of Tropical Storm Nana have dissipated in the central Atlantic, leaving just a tropical depression with top sustained winds of 30 mph. Another area of low pressure just south and east of Nana's remains is kicking up some wind and rain, but is not expected to strengthen.

Here is the final public advisory on Nana. Here is the storm track. There's not much to see from orbit.

In the eastern Caribbean, meanwhile, Tropical Storm Omar is lingering with top winds of 50 mph. It shows little motion for now, but is being felt in the Dutch Antilles - with wind and heavy rain for Aruba, Bonaire and Curacao. Forecasters are now considering storm watches from Puerto Rico to the Virgin Islands, and St. Martin, St. Eustatius and Saba.

Here is the latest advisory. Here is the forecast storm track. And here is the view from space. 

And off to the west, a disturbance off the coast of Nicaragua and Honduras has reached tropical depression status, with top winds of 30 mph. Now referred to as Tropical Depression 16, it is a threat to Central America, and is likely to become a tropical storm (Paloma) by tomorrow morning.
