While the extremely powerful Hurricane Franklin stays well out to sea, its impact will still be felt along the local coast as the Category 4 hurricane sparks rough surf and intense rip currents.

The National Weather Service’s Boston office is warning beachgoers of “dangerous” rip currents and high surf in the coming days due to Hurricane Franklin.

Life-threatening surf and rip currents generated by Franklin have already been affecting Bermuda and the Southeast U.S. coast, according to the National Hurricane Center. These conditions are expected to spread northward along the East Coast during the next couple of days.

“High surf and dangerous rip currents for south facing ocean beaches late Tuesday through Thursday,” the National Weather Service’s Boston office wrote in its forecast.

“If heading to the beach sometime late Tue through Thu then be aware that there is an increasing risk for rip currents/high surf due to distant #Franklin Stay tuned!” NWS Boston tweeted.

On the forecast track, the center of Franklin is expected to pass well to the west of Bermuda on Wednesday.

Maximum sustained winds are near 145 mph with higher gusts. Additional strengthening is possible, but gradual weakening is expected to begin late Tuesday.

Meanwhile in the Gulf, Tropical Storm Idalia on Monday was nearing hurricane strength as it approached western Cuba. Life-threatening storm surge and dangerous winds were becoming likely for parts of Florida, according to the National Hurricane Center.

“There is a danger of life-threatening storm surge inundation along portions of the Florida Gulf Coast where a Storm Surge Warning is in effect, including Tampa Bay and the Big Bend region of Florida,” the National Hurricane Center wrote in its alert.

“Inundation of 8 to 12 feet above ground level is expected somewhere between Chassahowitzka and Aucilla River,” the center added. “Residents in these areas should follow any advice given by local officials.”

Hurricane conditions are expected along the Florida Gulf Coast, with the potential for destructive winds where the core of Idalia moves onshore. Strong winds will also spread inland across portions of northern Florida near the track of the center of Idalia.

Areas of flash and urban flooding are expected across portions of the west coast of Florida, the Florida Panhandle, and southern Georgia Tuesday into Wednesday, spreading into portions of the eastern Carolinas Wednesday into Thursday.
