Today Tropical Storm Alex is rapidly crawling across the island of Bermuda. It is approaching northeast at almost 30 mph with sustained maximum winds of 65 mph.
A tropical storm warning is still in effect today in Bermuda as the center of Alex passes north of the island. For the American continent, the storm is producing dangerous waves and currents on the coast from the Carolinas to the Delmarva Peninsula.
Alex will continue to accelerate toward the sea, becoming a posttropical system today as it moves over colder waters and into drier air and more wind shear.
Computer model predictions also match on a northeasterly track.
Spaghetti or graphic models show a series of individual computer prediction models together on a map. They are useful for giving an idea of whether or not several models agree on the trajectory of the storm, but do not address the expected intensity of the storm, winds, floods, and the potential for storm surge or other data.

Alex’s weekend hits
Alex became the first named storm of the Atlantic hurricane season after heavy rains and floods in South Florida and the Bahamas on Saturday. It formed early Sunday in the Atlantic, about 165 miles east-northeast of Fort Pierce, Florida.
Alex started out as Agatha in the Eastern Pacific, who graduated in the early hours of Saturday, May 28th. It became a hurricane a day later before it made landfall last Monday in southern Mexico.
It collapsed in a remaining disturbance on Tuesday morning before moving to the Gulf of Mexico. However, the riot was difficult to regain strength as it moved northeast.
Although the wind shear and drier air at the top actually weakened this uneven system as it approached South Florida from Friday night to Saturday, it still brought heavy rains and flooding.
The disturbance regained its strength and better organization as it moved away from the Florida coast on Saturday night and became the first named storm of the season on Sunday morning, Tropical Storm Alex.
Before the storm it was Alex, it was the potential tropical cyclone one. The system brought flooding to parts of South Florida. Heavy rainstorms caused sudden flooding in Miami.
In addition, the Miami National Weather Service says several areas received more than a foot of rain from the PTC One.
The storm also brought flood rains to Cuba. Three people were killed in a storm that hit the island, according to the Associated Press.
The wreckage of Hurricane Agatha killed at least 9 people in Mexico last week as the storm crossed the Pacific to the Gulf of Mexico.
A tropical disturbance crossing from one basin to another is not particularly uncommon, although it is usually the debris that regenerates rather than an intact system surviving the crossing. And, the most common direction is the Atlantic to the Pacific, not the other way around.
For a recent account of the remains of one basin being redeveloped in the other, that happened only last year. The Atlantic’s Grace dissipated over Mexico, but its remaining circulation became Marty in the Pacific. In 2020, Amanda in the Pacific collapsed but took Cristobal to the Atlantic.
Over the past 50 years, 12 tropical systems have remained completely intact as they crossed basins. The last one was Otto in 2016, tracking from the Atlantic to the Pacific. In the other direction, the most recent storm was Hermine in 2010.
