Isaac is expected to continue moving west-northwest through Saturday. On the forecast track, the center of Isaac will be near or over Hispanola Friday, and move over southeastern Cuba on Saturday.
In anticipation of Isaac's approach, the Florida State Emergency Response Team was partially activated Thursday, Gov. Rick Scott said.
"Obviously we are hoping Isaac doesn't hit Florida, but we must take every precaution," Scott said. “That’s what we’re doing on a state level, and it’s what everyone should be doing on a family and personal level. If you haven’t already, get prepared and get a plan.”
Regardless of where you live in Florida, state emergency officials said you can be impacted by a tropical weather system. It is so important that everyone does their part to prepare for a storm because it could happen at any time, the governor said. Hurricane Andrew serves as a strong reminder that “it only takes one.”

Joyce, which was moving west-northwest at 14 mph, was expected to continue that general motion for the next few days. The storm had become less organized Thursday afternoon, said forecasters at the National Hurricane Center.
