Torrential downpours, high winds, dangerous surf and beach erosion are all possible impacts of Sandy as the storm moves east of Florida.
Sandy is expected to pass a couple hundred miles to the north and east of Miami Friday as a massive Category 1 hurricane.
"Friday morning is when Miami will receive the worst of Sandy," AccuWeather.com Meteorologist Steve Travis said.
The immediate coast could receive 2-4 inches of rain from the outer bands of Sandy, causing localized flooding concerns. However, 50-60 miles inland, rainfall will be much less with amounts of half an inch more likely.
Sustained winds of 30-40 mph and tropical storm-force wind gusts are likely in Miami. There could be some incidences of downed trees, power outages and minor roof damage with this magnitude of wind.
Rough surf, numerous and strong rip currents and beach erosion are other major concerns as Sandy moves east of the area. Waves as high as 12-14 feet will pound the coast Friday morning.
