Fernand was a tropical storm in the Sargasso Sea Sunday morning Eastern time, the National Hurricane Center said in its latest advisory.

Fernand is the sixth named storm to form in the Atlantic in 2025.

Forecast wind speeds and direction

Where will it rain?

Flash flooding can occur well inland and away from the storm’s center. Even weaker storms can produce excessive rainfall that can flood low-lying areas.

Tracking Fernand’s rainfall

When a storm comes close enough to land, signals from the United States radar network will begin to bounce off the rainfall within a tropical cyclone, making it easier to locate the more intense section of the storm and the heaviest rainfall. During hurricanes, the storm’s center will be the area on radar void of rain called an eye and completely encircled by the most intense winds and rain called the eye wall. Spiraling out from the center will be bands of rain that vary in intensity.

What is the risk of rip currents?

Rip currents, even from distant storms, are the third-highest cause of death related to hurricanes, after inland flooding from excessive rain and storm surges, according to the Weather Service. This year, the Hurricane Center has started providing rip current forecasts.

Tracking power outages

The damaging winds from Fernand caused power outages along the storm’s path.

What does the storm look like from above?

Satellite imagery can help determine the strength, size and cohesion of a storm. The stronger a storm becomes, the more likely an eye will form in the center. When the eye looks symmetrical, that often means the storm is not encountering anything to weaken it.

The Atlantic hurricane season started on June 1 and runs through Nov. 30.

In late May, the National Oceanic and Atmospheric Administration, the parent agency of the National Weather Service, predicted that this would be an above-average season, with 13 to 19 named storms. In early August, a revised forecast from NOAA predicted 18 named storms for the season and said up to nine of them could become hurricanes.

Last year, there were 18 named storms, 11 of which became hurricanes. Five of those hurricanes became what the Hurricane Center calls “major,” or Category 3, 4 or 5 on the Saffir–Simpson scale.

Hurricane Beryl was one of two Category 5 hurricanes last year, and it set records for the earliest point in a season that a storm had grown so big. In contrast, this year was one of the slowest starts to a season in 20 years.

Like the other most powerful storms last year, Beryl’s quick intensity was a result of above-average ocean temperatures. But this year, in the main region where storms typically form, the ocean heat content — the measure of thermal energy stored in the ocean that can fuel storms — has been slightly below average in June.

Experts think it is probable that a major hurricane will make landfall in the U.S. this season. Climate experts have warned intense storms like these are more likely to occur, with more rapid intensification likely in a warming world.

Last year was also one of the most costly for hurricanes in the United States. Hurricanes Helene and Milton combined caused about $113 billion in damages and more than 250 deaths. This May, the Trump administration said it would no longer maintain a database of so-called billion-dollar disasters.

The Trump administration has slashed the number of employees at many of the agencies traditionally responsible for planning for and responding to natural disasters, including NOAA, the Weather Service and the Federal Emergency Management Agency.

Climate change is also affecting the amount of rain that storms can produce. In a warming world, the air can hold more moisture, which means a named storm can hold and produce more rainfall, like Hurricane Harvey did in Texas in 2017, when some areas received more than 40 inches of rain in less than 48 hours.

Researchers have also found that storms have slowed down, staying over areas for more extended periods, over the past few decades.

Sources and notes

Tracking map Tracking data is from the National Hurricane Center. The map shows probabilities of at least 5 percent. The forecast is for up to five days, with that time span starting up to three hours before the reported time that the storm reaches its latest location. Wind speed probability data is not available north of 60.25 degrees north latitude.

Wind arrivals table Arrival times are generated from a New York Times analysis of National Hurricane Center data. Geographic locations use data from the U.S. Census Bureau and Natural Earth. Time zones are based on Google. The table shows predicted arrival times of sustained, damaging winds of 58 m.p.h. or more for select cities with a chance of such winds reaching them. If damaging winds reach a location, there is no more than a 10 percent chance that they will arrive before the “earliest reasonable” time and a 50 percent chance they will arrive before the “most likely” time.

Radar map Radar imagery is from the National Oceanic and Atmospheric Administration via Iowa State University. These mosaics are generated by combining individual radar stations that comprise the NEXRAD network.

Storm surge map Storm surge data is from the National Hurricane Center. Forecasts only include the United States Gulf and Atlantic coasts, Puerto Rico, and the U.S. Virgin Islands. The actual areas that could become flooded may differ from the areas shown on this map. This map accounts for tides, but not waves and not flooding caused by rainfall. The map also includes intertidal areas, which routinely flood during typical high tides.

Rip currents map Rip current data is from the National Hurricane Center. Rip current risk shown is not always associated with active tropical cyclones.

Historical map Storm paths are from the National Oceanic and Atmospheric Administration’s HURDAT database. Only storms with names that formed after the year 2000 and that are within 50 miles of the potential landfall location are shown.
