    In a hurry? Here’s what’s happening with Tropical Storm Helene in less than a minute.

    Hurricane watches and warnings have been issued across Florida as Tropical Storm Helene continues to strengthen, according to the latest advisory from the National Hurricane Center.

    Time is running out to complete preparations for what is expected to be a major hurricane by the time it makes landfall Thursday.

    Current predictions have Helene rapidly intensifying as it moves north in the Gulf of Mexico. Winds could get up to 120 mph over the next 36 hours, according to the National Hurricane Center. That would make Helene a Category 3 hurricane.

    AccuWeather forecasters are predicting Helene could reach Category 4 strength as it moves into the extremely warm waters in the Gulf of Mexico, with maximum sustained winds ranging between 130 and 156 mph.

    Where will Tropical Storm Helene make landfall?

    Landfall is expected along the northeast coast of the Gulf of Mexico late Thursday or Thursday night, according to the National Hurricane Center.

    The highest landfall probability is somewhere along the eastern part of the Florida Panhandle — perhaps in the Big Bend area — late Thursday evening, according to AccuWeather.

    A possible track farther to the southeast, over the Florida Peninsula, could mean an earlier landfall Thursday.

    “Everyone along the Florida Panhandle and Big Bend region needs to be prepared for hurricane impacts,” said AccuWeather Lead Hurricane Expert Alex DaSilva, adding the system has the potential to become the strongest hurricane landfall in the U.S. so far this season.

    “AccuWeather expert meteorologists expect this to be a highly impactful storm,” AccuWeather Chief Meteorologist Jon Porter said. “This could be the storm that the 2024 hurricane season is remembered for.”

    Don’t focus on the cone! Helene is large storm, impacts will be widespread

    Tropical Storm Helene is expected to grow even larger before it makes landfall Thursday and impacts can be expected hundreds of miles from the center.

    “This can be a large hurricane with life-threatening impacts such as storm surge and flooding rain hundreds of miles away from where the storm makes landfall,” Porter said.

    “Storm surge, wind, and rainfall impacts will likely extend well away from the center and outside the forecast cone, particularly on the east side,” the National Hurricane Center said.

    “In addition, the fast forward speed while Helene crosses the coast will likely result in farther inland penetration of strong winds over parts of the southeastern United States after landfall.”

    Most of Florida under state of emergency

    Gov. Ron DeSantis expanded a state of emergency Tuesday to 61 of Florida’s 67 counties, including all of the Florida Panhandle.

    Counties under the state of emergency are: Alachua, Baker, Bay, Bradford, Brevard, Calhoun, Charlotte, Citrus, Clay, Collier, Columbia, DeSoto, Dixie, Duval, Escambia, Flagler, Franklin, Gadsden, Gilchrist, Glades, Gulf, Hamilton, Hardee, Hendry, Hernando, Highlands, Hillsborough, Holmes, Jackson, Jefferson, Lafayette, Lake, Lee, Leon, Levy, Liberty, Madison, Manatee, Marion, Monroe, Nassau, Okaloosa, Okeechobee, Orange, Osceola, Pasco, Pinellas, Polk, Putnam, Santa Rosa, Sarasota, Seminole, St. Johns, Sumter, Suwannee, Taylor, Union, Volusia, Wakulla, Walton, and Washington counties.

    An announcement that sustained winds of 39 to 73 mph are possible within the specified area within 48 hours in association with a tropical, subtropical, or post-tropical cyclone.

    How strong is Tropical Storm Helene and where is it going?

    At 5 a.m. EDT, the center of Tropical Storm Helene was located near latitude 20.7 North, longitude 86.2 West.

    Helene is moving toward the northwest near 9 mph. This motion should continue through this morning, followed by a general northward motion beginning later today and continuing through Friday.

    ➤ Track all active storms

    On the forecast track, the center of Helene will pass near the northeastern coast of the Yucatan Peninsula this morning, move across the eastern Gulf of Mexico on later today and Thursday, and reach the Big Bend coast of Florida late Thursday.

    Maximum sustained winds are now near 65 mph, with higher gusts.

    Strengthening is forecast, and Helene is expected to become a hurricane later today.

    The storm is forecast to rapidly strengthen over the eastern Gulf of Mexico and become a major hurricane on Thursday.

    Tropical-storm-force winds extend outward up to 175 miles from the center.

    Key messages from the National Hurricane Center: What you need to know about Tropical Storm Helene

    1. Helene is forecast to intensify and be near hurricane strength when it passes near the northeastern coast of the Yucatan Peninsula during the next several hours, where a Hurricane Warning is in effect.
    2. Helene is expected to rapidly intensify and grow in size over the eastern Gulf of Mexico. There is a danger of life-threatening storm surge along the entire west coast of the Florida Peninsula and Florida Big Bend. The highest inundation levels are expected along the coast of the Florida Big Bend. Residents in those areas should follow advice given by local officials and evacuate if told to do so.
    3. Damaging hurricane-force winds are expected along portions of coast of the Florida Big Bend, where a Hurricane Warning is now in effect. Preparations to protect life and property should be completed by early Thursday since tropical storm conditions are expected to begin within this area on Thursday.
    4. Tropical Storm Helene will bring heavy rain to portions of the western Caribbean with potentially significant flooding across western Cuba and the northeastern Yucatan Peninsula. Considerable and potentially life-threatening flash and urban flooding is expected across portions of Florida, the Southeast, the Southern Appalachians, and the Tennessee Valley beginning today through Friday. This includes the risk of landslides across the southern Appalachians. Widespread minor to moderate river flooding is likely, and isolated major river flooding is possible.

    Current forecast: Where is Tropical Storm Helene going and how strong could it get?

    • As of 5 a.m.: 65 mph
    • 12 hours: 80 mph
    • 24 hours: 105 mph
    • 36 hours: 120 mph

    What impact could Tropical Storm Helene have and what areas could be affected?

    Wind: Hurricane conditions are expected in the hurricane warning area in Mexico during the next several hours, with tropical storm conditions already ongoing. Hurricane conditions are expected within the U.S. hurricane warning area late Thursday. Hurricane conditions are possible for the western portion of Cuba later today. Tropical storm conditions are expected to begin in the warning area in Cuba during the next several hours.

    Tropical storm conditions are expected in southern Florida later today and spreading northward through Thursday. Tropical storm conditions are possible within the tropical storm watch area beginning Thursday and Thursday night.

    Storm surge: The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide:

    • Ochlockonee River, FL to Chassahowitzka, FL…10-15 ft
    • Chassahowitzka, FL to Anclote River, FL…6-10 ft
    • Indian Pass, FL to Ochlockonee River, FL…5-10 ft
    • Anclote River, FL to Middle of Longboat Key, FL…5-8 ft
    • Tampa Bay…5-8 ft
    • Middle of Longboat Key, FL to Englewood, FL…4-7 ft
    • Englewood, FL to Flamingo, FL…3-5 ft
    • Charlotte Harbor…3-5 ft

    ➤ Why is a storm surge so dangerous?

    Rainfall: Tropical Storm Helene is expected to produce total rain accumulations of 4 to 8 inches over western Cuba, the Cayman Islands and the northeast Yucatan Peninsula, with isolated totals around 12 inches. This rainfall brings a risk of considerable flooding.

    Over the Southeastern U.S., Helene is expected to produce total rain accumulations of 5 to 10 inches with isolated totals around 15 inches. This rainfall will likely result in areas of considerable flash and urban flooding, with areas of significant river flooding. Landslides are possible in areas of steep terrain in the southern Appalachians.

    ➤ Excessive rainfall forecast

    Surf: Swells generated by Helene will affect the southern coast of Cuba and the Yucatan Peninsula of Mexico during the next couple of days. Swells will spread northward toward the west coast of Florida and the northeastern Gulf Coast later today and Thursday.

    Tornadoes: A tornado or two may occur tonight over parts of the western Florida peninsula and southern Alabama. The risk of tornadoes will increase on Thursday, expanding across Florida and into parts of Georgia and South Carolina.

    NHC launches new cone of concern: What to know

    The National Hurricane Center launched a new, experimental cone of concern in August. Here’s what’s changed.

    The National Hurricane Center first launched its new “cone of concern” for Hurricane Ernesto on Aug. 14.

    Ernesto stayed well away from Florida and the U.S., so residents didn’t see many differences between the original and new cone. One of the biggest differences between the two is that the new cone will show wind warnings issued for interior counties, not just those on the coast.

    Both cones will be visible on the Hurricane Center’s website. Find the new cone by going to the graphics page for the storm, then click on “New Experimental Cone,” which will be highlighted in red.

    Differences you’ll see:

    • Watches and warnings for inland counties, not just coastal areas.
    • White transparent shading for the entire five-day forecast, instead of white stippling (dots) for the four- and five-day forecast.
