NOAA predicts at least three hurricanes this season
NOAA predicts the three major hurricanes in the 2025 hurricane season.
It's here. The 2025 Atlantic hurricane season begins Sunday, June 1.
Forecasts say the season will bring months of danger for millions of Americans, and the time to prepare starts well before the storms form.
In the Atlantic Basin, which includes storms that form in the Atlantic, the Caribbean Sea and the Gulf of America (formerly known as Gulf of Mexico), hurricane season lasts from June 1 until Nov. 30. Historically, 97% of all tropical cyclones in the Atlantic will form between those two dates.
In the eastern Pacific Basin, hurricane season started on May 15 and lasts until Nov. 30. (Tropical Storm Alvin formed in the the eastern Pacific Ocean on May 29, becoming the first named storm anywhere in the Northern Hemisphere this year.)
Officials with the National Oceanic and Atmospheric Administration said the most dangerous storms can quickly explode in intensity, so understanding forecasts, hurricane dangers and preparedness should be top-of-mind for residents well before storms start forming.
Here's a primer on what to know as hurricane danger ramps up in 2025.
When does hurricane season peak?
The peak of the Atlantic season is typically from mid-August until mid-October.
Hurricane season forecasts: How many storms are expected?
NOAA, FEMA cuts will impact hurricane season, experts warn
The Trump administration's budget cuts at NOAA and FEMA will have an adverse affect on how the U.S. responds to hurricanes, experts warn.
Federal forecasters on May 22 predicted a 60% chance of an above average season. (A typical year averages about 14 tropical storms, seven of which spin into hurricanes, based on weather records that date from 1991 to 2020.)
Specifically, NOAA is forecasting a range of 13 to 19 total named storms (winds of 39 mph or higher). Of those, 6 to 10 are forecast to become hurricanes (winds of 74 mph or higher), including 3 to 5 major hurricanes (Category 3, 4 or 5; with winds of 111 mph or higher).
Experts from Colorado State University said in their initial forecast released in early April that an active Atlantic hurricane season is likely. They predicted as many as 17 storms.
Of those 17 storms, researchers said that nine will become hurricanes.
A forecast from AccuWeather, which also came out in April, called for 13-18 named storms, of which 7-10 will be hurricanes.
Last year, 18 storms formed, including devastating Hurricanes Helene and Milton.
What state has the most hurricanes?
Florida, by a wide margin. Since accurate hurricane records began in 1851, more than 120 hurricanes have made landfall in the state of Florida. Texas is second, with 66 hits.
And according to NOAA, 40% of all U.S. hurricanes have hit Florida.
How can you prepare for hurricane season?
Check with your local government to see if you live in an evacuation zone.
Have a plan for where you would go if you need to evacuate and share that plan with friends or loved ones. Plan to travel only as far as you need to.
Write a family emergency plan with your family and/or close friends to decide how you would contact each other in an emergency, where you will go and what you will do. Keep copies on your phone, in your emergency supplies and share with family.
Put together a basic emergency kit, with water and shelf stable foods for up to a week, flashlights, back up batteries, a first aid kit and moist towelettes.
Review your insurance policies to ensure if you have adequate coverage, including flood coverage.
Store insurance policies, photos of your home and its contents and other important papers in a safe place, in electronic files and/or share copies with family members.

What is rapid intensification?
A rapid strengthening of a hurricane, when wind speeds increase by at least 35 mph in 24 hours.
It occurs when a tropical storm or hurricane encounters an extremely conducive environment for strengthening, according to Colorado State University hurricane researcher Phil Klotzbach. That environment consists of very warm water, low vertical wind shear and high levels of midlevel moisture.
What is storm surge?
Storm surge, the massive amount of water that builds up and comes ashore during a hurricane, is often the deadliest and most destructive threat from these storms.
It is characterized by water being pushed toward the shore by the force of the winds moving around the storm, NOAA said.
Storm surge has accounted for about half of all the deaths in hurricanes since 1970, according to the National Hurricane Center. It caused most of the 1,800 deaths in Hurricane Katrina in 2005.

Map Shows Where 3 States Warned About Floods in the Desert
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. The National Weather Service (NWS) has issued a flood watch for desert areas in southern California, southern Nevada, and northwestern Arizona, effective Wednesday, as heavy rain puts the region at risk for flooding. Why It Matters The heavy rain comes less than a week after remnants from Tropical Storm Alvin brought a surge of moisture to Arizona. AccuWeather Lead Hurricane Expert Alex DaSilva previously told Newsweek that the moisture was similar to the region's monsoon season, which doesn't typically begin until later in June. DaSilva said he expects more tropical storms to take a similar path as the Eastern Pacific hurricane season continues, meaning more heavy rain could be in the U.S. Southwest's future this summer. What to Know The watch is in effect for "portions of northwest Arizona, including the following areas, Lake Havasu and Fort Mohave, Lake Mead National Recreation Area, Northwest Deserts and Northwest Plateau, southeast California, including the following areas, Eastern Mojave Desert and San Bernardino County-Upper Colorado River Valley, and southern Nevada, including the following areas, Lake Mead National Recreation Area, Las Vegas Valley, Northeast Clark County, Sheep Range, Southern Clark County, Spring Mountains-Red Rock Canyon and Western Clark and Southern Nye County." The flood watch will remain in effect until 11 p.m. local time. A more severe flash flood warning has been issued in Northwest Arizona. In addition to causing floods, dirt and debris may also be present on the roads due to the surge in moisture. The Mojave National Preserve also asked people to be on the lookout for desert tortoises, which emerge after rain to hydrate and eat the vegetation. More rain is expected this evening, according to the NWS, with some thunderstorms potentially producing moderate to heavy rainfall. NWS meteorologist Jenn Soulat, who works at the Las Vegas office, told Newsweek that the moisture is unusual, given Las Vegas is currently in its dry season. Soulat attributed the surge in moisture to three storm systems that interacted with each other, including the remnants of Tropical Storm Alvin. She doesn't expect the flood watches to continue throughout the end of this week and warned people that triple-digit heat will soon return. A stock photo of a thunderstorm in the desert.

Flooding may occur in poor drainage and urban areas. Low-water crossings may be flooded." NWS in a forecast issued on Wednesday: "A storm system traversing the Southwest U.S. will continue to favor a regional threat of heavy showers and thunderstorms through tonight which may bring sufficient rainfall for at least scattered areas of flash flooding. This will include potential impacts to some of the area burn scar locations, local slot canyon areas, and also the normally dry washes. Up to a couple inches of new rainfall will be possible by early Thursday morning." What Happens Next The NWS Climate Prediction Center anticipates slightly above-normal precipitation for the region from June 10 to June 14, according to the six- to 10-day precipitation outlook. Normal rainfall is expected further out, for the eight- to 14-day outlook.

NOAA weather radios down in Huntsville for maintenance
NASHVILLE, Tenn. (WKRN) — In mid-May, the National Weather Service in Nashville underwent maintenance that caused weather radios to stop receiving alerts for a few days. Now, the National Weather Service office in Huntsville, Alabama, is going through the same maintenance, which will impact some counties in the News 2 viewing area. National Hurricane Center has made changes to forecasting – What you need to know The National Weather Service in Huntsville covers northern Alabama and three counties in southern Middle Tennessee: Lincoln, Franklin, and Moore. However, NOAA weather radios in the area won't receive alerts from Tuesday, June 3 to Thursday, June 5. According to NWS Huntsville, nothing else will be impacted by the maintenance. NOAA's predictions for summer 2025 just got even hotter During the three-day span, six radio transmitters will be down, including one in Winchester that covers three counties in Tennessee.

Florida weatherman warns DOGE cuts will lead to less accurate hurricane forecasts
As the Atlantic basin enters what experts forecast will be an 'above-normal' hurricane season, a Florida weatherman has an unsettling message for locals. John Morales, a meteorologist at NBC 6 South Florida, told viewers Monday night that he will no longer be able to accurately predict hurricanes due to the Trump administration's drastic cuts to weather and climate agencies. Morales, who has over three decades of experience reporting on weather in South Florida, began the forecast with a clip of his 2019 coverage of Hurricane Dorian. In the clip, Morales assured residents that the storm would turn, sparing the state from a direct impact. Morales' forecast proved to be accurate, and Dorian did not make landfall in Florida. After playing the clip, Morales said that while he was able to go on television six years ago and 'confidently' tell residents the storm would turn, he did not believe he could do the same this hurricane season. 'And I am here to tell you that I am not sure that I can do that this year because of the cuts, the gutting, the sledgehammer attack on science in general,' Morales said. Trump's cuts have led to massive staffing shortages at National Weather Service offices across Central and South Florida. As a result, Morales explained, less data is being collected due to fewer weather balloon launches. 'And what we're starting to see is that the quality of the forecast is becoming degraded,' Morales said. According to Morales, the administration's cuts could also decrease the number of hurricane reconnaissance mission flights carried out by the National Oceanic and Atmospheric Administration (NOAA). The agency's website states, 'Information from both research and reconnaissance flights directly contribute to the safety of people living along and visiting the vulnerable Atlantic and Gulf coasts.' Without this information, Morales warned, 'We may be flying blind, and we may not exactly know how strong a hurricane is before it reaches the coastline.' In May, NOAA predicted six to 10 hurricanes could hit the Atlantic this season. While the Trump administration has dismissed concerns that staffing cuts will impact service during hurricane season, which spans from June 1 to Nov. 30, two sources familiar with the matter told Reuters that the agency is already being stretched thin. Around 1,000 people, or 10% of NOAA's workforce, have reportedly been cut in recent weeks. Morales ended his forecast by urging viewers to take action, telling those watching at home to 'call your representatives and make sure that these cuts are stopped.'
