Tropical Storm Henri, a sad blob about 700 miles south of Newfoundland, is racing toward its demise in the North Atlantic. Our next chance at tropical development in the basin looks like it might come from the Cape Verde area, but as with every other system this year, it’ll struggle against wind shear and dry air if it manages to pull itself together.

Rain and a Hurricane Almost Changed the Course of History on September 11, 2001

Dennis Mersereau · 09/11/15 07:00AM

Everyone remembers the weather fourteen years ago. Every remembrance story, every “where were you when” conversation, every newscast before the attacks mentions how the sky was a brilliant, deep shade of blue the morning the world turned upside down. However, had the sky not been as clear as it was that day—if the hurricane off the coast of New England hadn’t ricocheted toward Canada—it’s very possible that the weather could have permanently changed the course of both American and world history.

Despite El Niño, Atlantic Ocean Keeps Cranking Out Tropical Cyclones

Dennis Mersereau · 09/08/15 02:35PM

This Saturday is the climatological peak of hurricane season in the Atlantic Ocean. It’s been a weird year with about seven storms so far, and we still have more than two months until it’s over. The season could have been worse if it weren’t for El Niño conditions out in the Pacific Ocean, which saves the butt of many coastal residents around the Atlantic during this time of the year.

Tropical Storm Grace formed near the Cape Verde Islands this afternoon. It will follow roughly the same path as Danny and Erika before it, and it’ll probably fizzle out in the dry air and wind shear. Meanwhile, Fred—a questionable tropical depression at best—is still hanging on by a thread. Neither storm will pose a threat to land in the next five days.

A Typhoon and a Hurricane Are the Same, So Why Do We Call Them Different Names?

Dennis Mersereau · 09/01/15 03:57PM

A tropical cyclone is an iconic storm that strikes fear (or laughter) in the heart of coastal residents around the world. Most of these low pressure systems over the ocean are weak, but some can grow into monsters. If they’re all the same kind of storm, though, why do we call them different names around the world?

Tropical Storm Erika Croaks, But Heavy Rain Is Still Possible in Florida 

Dennis Mersereau · 08/29/15 04:45PM

Remember Erika? The mountains of Hispaniola and Cuba tore it to bits, and the National Hurricane Center declared it dead at 9:30 this morning. All that tropical moisture has to go somewhere, though, and Florida could still see several inches of rain from its remnants. Tropical downpours on saturated soil will lead to the potential for dangerous flooding, so it’s not something to take lightly.

Deadly Flash Flooding Possible as Tropical Storm Erika Aims for Puerto Rico

Dennis Mersereau · 08/27/15 05:43PM

Tropical Storm Erika is a mess today, barely holding itself together as it draws closer to Puerto Rico. Despite its ragged appearance, the storm is producing very heavy rain along its path; devastating flooding on the small island of Dominica killed at least four people last night. Erika is still a threat to Florida, and current forecasts show the storm closing in on the Sunshine State as a hurricane early next week.

Tropical Storm Erika Could Break Florida's 3,594-Day Hurricane-Free Streak

Dennis Mersereau · 08/26/15 02:43PM

We’re fast approaching ten years since the last hurricane made landfall in Florida. Hurricane Wilma struck the southwestern tip of the state on October 24, 2005, and ever since then, this hurricane-prone panhandle has been incredibly lucky. That could change in the coming days if the forecasts hold true.

Tropical Storm Erika Could Either Threaten the U.S. Next Week or Fall Apart into Nothing

Dennis Mersereau · 08/25/15 02:53PM

Social media is buzzing this afternoon over the possibility that Tropical Storm Erika could strengthen into a hurricane and threaten the U.S. East Coast next week. However, the forecast is far from certain, and the storm could either make landfall or fall apart or swerve out to sea. Predicting the future is hard, and Tropical Storm Erika represents one of those frustrating limits of weather forecasting.

Understanding Storm Surge, the Deadliest and Most Overlooked Hazard in Hurricanes

Dennis Mersereau · 08/24/15 02:57PM

Whenever a hurricane threatens land, almost all of the focus is on preparing for the strong winds. It’s not always the wind that gets you—it’s the water. The storm surge in a hurricane is arguably the greatest threat with these landfalling terrors, and it’s one that too many people seem to ignore until it’s too late.

Hawaii Under Hurricane Threat; Atlantic's Danny Explodes into a Major Hurricane

Dennis Mersereau · 08/21/15 03:41PM

Summer weather is characterized by long periods of mind-numbing monotony followed by short bursts of terrifying chaos. We’re in one of those chaotic periods right now, where the August doldrums collapsed and gave us a tiny but powerful hurricane in the Atlantic, and a potential hurricane threatening Hawaii next week.

Hurricane Danny Eyes Caribbean as Three More Storms Try to Take Shape

Dennis Mersereau · 08/20/15 03:18PM

Talk about feast or famine—it’s like the tropics looked at the calendar and decided that they needed to shift into high gear. Not only are we tracking Hurricane Danny as it makes its way toward the Caribbean this weekend, but there are three more systems—two in the Atlantic and one in the central Pacific—that could try to develop into tropical cyclones as we head through next week.

'Twin Typhoons' Spinning in Western Pacific, Taiwan and Japan at Risk

Dennis Mersereau · 08/19/15 02:55PM

Fraternal twins were born in the western Pacific Ocean this weekend. Two typhoons—Goni and Atsani—developed at the same time within a few hundred miles of each other, but each storm took on a life of its own and will have dramatically different outcomes. Typhoon Goni poses the greatest threat to land, coming dangerously close to countries like Taiwan and Japan.

Tropical Storm Danny Forms in Atlantic, Moving Toward Caribbean (Updated)

Dennis Mersereau · 08/18/15 02:35PM

A new tropical storm in the Atlantic Ocean is going to get a lot of play in the news over the next couple of days as official forecasts expect it to become Hurricane Danny by the end of this weekend. The system has plenty of obstacles along its path and it’s a long way from land, but we’re nearing the peak of hurricane season, so it’s worth watching closely.

Dennis Mersereau · 08/17/15 03:46PM

An interesting feature southwest of the Cape Verde Islands is slowly getting its act together, and it’s likely to become a tropical depression or tropical storm over the next few days as it moves west toward the Caribbean. Its future is uncertain right now, but it bears watching given its location and the time of year.

Typhoon Soudelor is poised to make landfall on the east coast of Taiwan with winds of about 115 MPH, which makes it the equivalent of a category three on the Saffir-Simpson Scale. The island can expect destructive winds, torrential rainfall, landslides, and a damaging storm surge in coastal communities. Soudelor will make a second landfall in China on Sunday afternoon (local time) as a significantly weaker storm, but still a heavy rain producer.

Typhoon Soudelor Could Strike Taiwan With 140 MPH Winds on Friday

Dennis Mersereau · 08/05/15 03:47PM

Typhoon Soudelor poses a grave threat to Taiwan later this week as the powerful tropical cyclone swirls closer to the island off the southeast coast of China. The storm has weakened since it produced 180 MPH winds on Monday, but it’s predicted to restrengthen to a destructive category four before landfall on Friday.
