Is a hurricane coming toward Palm Beach County, Florida? Expected impacts from Tropical Storm Erin
No tropical storm — or hurricane — watches or warnings have been issued for Florida or the United States, and it's too early to tell whether Erin will impact the U.S., according to the National Hurricane Center, National Weather Service and Florida Division of Emergency Management.
Even if Erin does avoid a landfall in Florida, "there will be a significant increase in seas, surf and rip currents along the East Coast beaches next weekend into the following week," said AccuWeather Senior Meteorologist Chad Merrill.
"Dangerous conditions may develop in Bermuda and parts of the Bahamas, as well."
How strong is Tropical Storm Erin and where could it go? See the scenarios
Several factors favor the strengthening of Tropical Storm Erin, including a lack of dust and wind shear, along with warm water temperatures, according to AccuWeather.
As Erin moves west across the Atlantic, it's expected — at this time — to begin a curve to the north Thursday or Friday, keeping the main part of the storm north of the islands in the northeastern Caribbean. However, depending on Erin's exact track, Puerto Rico and Hispaniola could get some rough surf and perhaps squalls.
"Erin will be guided along by the northeast trade winds initially and then the clockwise circulation around the massive Bermuda High over the central Atlantic," AccuWeather Lead Hurricane Expert Alex DaSilva said.
"It is the shape of that oceanic high, as well as the approach of a cool front and dip in the jet stream near the Atlantic Coast, that will determine the exact track of the projected major hurricane as it approaches the Atlantic Coast of the United States next week."
The scenarios, according to AccuWeather are:
"If the Bermuda High remains fairly round or yields to the approaching cool front and jet stream dip, Erin is likely to turn to the north before reaching the U.S.
"If the Bermuda High extends well to the west, it could block the potential major hurricane's northward path. The result would be a potential track very close to or onshore in the U.S., probably somewhere from the Carolinas north."
Could Tropical Storm Erin impact Palm Beach County, Florida?
It's still early to tell yet what impacts Tropical Storm Erin could have on Florida or the United States, although forecasters said rough surf and dangerous rip currents are possible along the east coast as Erin approaches.
Officials warn residents should be prepared and closely monitor the storm that's expected to become a major hurricane later this week.

Key messages from the National Hurricane Center: What you need to know about Tropical Storm Erin
Erin has not become significantly better organized overnight.
The tropical storm continues to move quickly to the west.
Strengthening is expected as Tropical Storm Erin enters an area of low wind shear and increasingly warm water temperatures.
Erin is expected to become a major hurricane in about five days, although "there is significant uncertainty in intensity predictions" at this time.
It is too early to determine what impacts, if any, Erin may bring to the northern Leeward Islands, Bermuda, or the east coast of the United States.

A few more storms possible across Maryland Thursday
Patchy fog will start to develop tonight as humidity stays high, and it's going to feel muggy with overnight lows only dropping into the upper 60s to low 70s. A few stray showers could linger, but most of the steady rain will wind down after sunset. Thursday stays warm and sticky, with highs pushing near 90 degrees. Scattered showers and thunderstorms will fire up again as a cold front moves through, and some of those storms could bring heavy downpours and gusty winds before things start to quiet down later in the evening. By Friday, you'll notice a big difference — drier air moves in from the north, knocking humidity down and bringing highs back into the 80s under brighter skies. It will feel much more comfortable heading into the weekend. Saturday looks pleasant, with comfortable humidity and highs in the 80s, but the break from the heat won't last long. By Sunday and Monday, the mugginess returns, along with highs in the low-to-mid 90s and heat index values near 100. Also worth watching — strengthening Tropical Storm Erin is forecast to make a close pass to the North Carolina coast early next week. While it's not expected to have a direct impact on Maryland's weather, it will increase the risk of dangerous rip currents at Maryland and Delaware beaches beginning this weekend and continuing into early next week. Another cold front early next week will bring another round of storms followed by a stretch of cooler, less humid weather by midweek. Even with that cooldown, any storms through early next week could still pack a punch with heavy rain, frequent lightning, and gusty winds.

Tropical Storm Erin forecast to be hurricane by Friday
Tropical Storm Erin is forecast to become a hurricane by 2 a.m. Friday and a major one by 2 p.m. Sunday. Image by National Hurricane Center Aug. 13 (UPI) -- Tropical Storm Erin is slightly intensifying and forecast to become a hurricane on Friday morning over the central tropical Atlantic with a chance of ultimately affecting the U.S. East Coast, the Bahamas and Bermuda next week, the National Hurricane Center said Wednesday. For the first time since Erin became a tropical storm Monday morning, intensity increased, though just 5 mph, to maximum sustained winds of 45 mph, with gradual strengthening during the next two days forecast, the NHC said in its 5 p.m. EDT update. Forecasters said Erin will become a major hurricane, with winds of at least 111 mph, by 2 p.m. Sunday. It would be the first hurricane of the Atlantic season with winds at least 74 mph. Beryl was the first hurricane last year on June 24. The storm is about 1,200 miles from east of the Northern Leeward Islands. Erin was moving westward at 17 mph and will shift to a north-westward track beginning Thursday night and into the weekend, the NHC said. The NHC's "cone" doesn't track Erin past Monday, and NHC forecasters remind that they have an average error of 150 to 214 miles at days four and five. In the latest discussion, NHC forecaster Jack Beven said there is a "greater than normal uncertainty about what impacts Erin may bring to portions of the Bahamas, the East Coast of the United States and Bermuda." But he said: "The risk of dangerous surf and rip currents across the western Atlantic basin next week is increasing." By this weekend, swells are forecast to cause life-threatening surf and rip current conditions, the NHC said. Alex Sosnowsky, an AccuWeather senior forecaster, said there is concern that residents, visitors, cruise lines, and shipping and fishing ventures "could pass paths with a powerful hurricane." With a track farther to the east, Bermuda could be directly in the path as a major hurricane. He said a farther west scenario would mean a greater risk of strong winds, rain and coastal flooding in the U.S., including eastern North Carolina, Long Island, New York and southeastern New England. "Families heading to U.S. Atlantic beaches for a late-summer vacation next week need to be extremely cautious when venturing into the surf," AccuWeather Lead Hurricane Expert Alex DaSilva said. "More than 50 people have lost their lives to rip currents and rough surf at beaches across the country so far this year, without any major hurricane nearby." There are no warnings or coastal watches in effect. But those in the northern Leeward Islands, the Virgin Islands and Puerto Rico should monitor Erin's progress. The previous four named Atlantic storms this year were Andrea, Barry, Chantal and Dexter. None of them became hurricanes, and Chantal was the only one to make landfall in the United States, causing significant flooding in North Carolina. Helene struck that state last year as a tropical storm, causing an estimated $53 billion in damage, after hitting western Florida as a Category 4 hurricane. Four other hurricanes made landfall in the United States in 2024: Beryl, Debby, Francine and Milton.
