Despite pushing away from Florida's peninsula, Isaac will continue to pose hazards Tuesday.
Isaac will make landfall over the central Gulf Coast later Tuesday.
The AccuWeather.com Hurricane Center has Isaac's exact position, as well as other latest statistics.
While Isaac remained a tropical storm to close out the weekend, the waters of the eastern Gulf of Mexico are warm enough to allow Isaac to strengthen into a hurricane prior to making landfall.
The good news for those across the Florida Peninsula is that Isaac will be pushing away as it undergoes strengthening.
That does not mean a quiet Tuesday is shaping up for Miami, Naples, Tampa and Orlando. Instead, the peninsula will remain on Isaac's extremely active side.
Squally bands of torrential rain and thunderstorms will continue to stream across central and southern Florida into Tuesday. Such squalls will be capable of producing blinding downpours and strong, gusty winds.
A couple of the squalls can also produce quick, spin-up tornadoes.
People should be prepared for sporadic power outages and areas of rather intense urban and flash flooding.
Strong tropical storm-force winds, capable of causing more significant tree damage, will buffet southwestern Florida, including Naples.
The large circulation of Isaac can cause areas of minor coastal flooding along the western and southern coastline of the Peninsula into the middle of the week.
"As Isaac moves up over the eastern Gulf, a return flow from the west and southwest in the wake of the storm can bring a storm surge along the Florida west coast," stated AccuWeather.com Expert Senior Meteorologist Alex Sosnowski.
Unsettled weather for the extended Labor Day weekend will be across the Southeast, Upper Midwest, northern Rockies and the Four Corners.
Tropical Depression 14-E is several hundred miles southwest of Mexico and is expected to strengthen slowly into a tropical storm.
A stormy weather pattern will prevail through September across much of southern South America.
While lulls in tropical activity in the Atlantic will continue, a rapid end to the hurricane season in September does not always occur during an El Niño.
The combination of moisture from Erika and a non-tropical system will drench areas from Florida to the South Carolina coast through the middle of the week.
Heat will be erased by an autumnlike air mass across parts of northern Europe.
