The latest on the search for the two Florida teens who went missing while on a fishing trip off Florida's Atlantic coast:

9:45 a.m.

The Coast Guard says its search for two missing teenage boaters will press forward at least into Friday.

Chief Petty Officer Ryan Doss says crews will continue surveying waters from Florida up through South Carolina throughout the day and overnight. A determination on plans for beyond that haven't been made, but Doss says there are no immediate plans to call the search off, since it is still believed there's a chance the 14-year-olds, Perry Cohen and Austin Stephanos, are still alive.

There are many unknowns about the boys, including whether they have life jackets on, might have a cooler or some other object to cling to, or have drinking water or food. The Coast Guard makes its decision erring on the side of best-case scenarios, while still noting there are limits to how long humans can survive in the open ocean.

The teens have been missing since leaving on a fishing boat on Friday.
