Storm tracker: Chantal weakens into post-tropical cyclone
As of 11 p.m. ET on July 7, Chantal was located about 85 miles northeast of Cape May, New Jersey, with maximum sustained winds around 25 mph with higher gusts. By Tuesday morning, the system was located around 100 miles south of Long Island, New York.
Hurricane center forecasters said Chantal is moving toward the northeast and this motion is expected to continue with an "increase in forward speed" into Tuesday. Due to its forward motion and modest wind field, the cyclone's wind field is becoming less defined, the NHC said.
"Post-Tropical Cyclone Chantal could open up into a trough of low pressure by Tuesday morning," the hurricane center said Monday night.
Chantal could produce an additional inch of rain across portions of New Jersey and Long Island Monday night into Tuesday morning, with an inch or two also possible across portions of Cape Cod, Martha's Vineyard, and Nantucket early Tuesday morning.
Additionally, life-threatening surf and rip current conditions are expected to continue at beaches along the U.S. east coast from northeastern Florida to the Mid-Atlantic states for the next day or so, the NHC said.
In the Pacific, the hurricane center said an area of low pressure could form several hundred miles offshore of southwestern Mexico late this week.
Forecasters said environmental conditions are expected to only be marginally conducive for development of this system, and the hurricane center said the storm has a 10% chance of formation through the next seven days.

How do hurricanes form?
Hurricanes are born in the tropics, above warm water. Clusters of thunderstorms can develop over the ocean when water temperatures exceed 80 degrees Fahrenheit. If conditions are right, the clusters swirl into a storm known as a tropical wave or tropical depression.
A tropical depression becomes a named tropical storm once its sustained wind speeds reaches 39 miles per hour. When its winds reach 74 mph, the storm officially becomes a hurricane.
Prepare now for hurricanes
Delaying potentially life-saving preparations could mean waiting until it's too late. "Get your disaster supplies while the shelves are still stocked, and get that insurance checkup early, as flood insurance requires a 30-day waiting period," NOAA recommends.

Watch Texas Flood In Minutes With Shocking Time-Lapse
News out of Texas this Fourth of July weekend has been nothing short of devastating. The death toll from severe flooding has risen to at least 108 people, including 30 children, and continues to climb. TikTok user @kelseycrowder_ posted a timestamped compilation of clips showing how the Frio River, about 80 miles west of San Antonio, flooded while people were out celebrating the holiday. The clip starts at 5:43 p.m., when it was a relatively normal Fourth of July on the then-calm river: Just about half an hour later, floodwaters are rushing by: Check out how wide the river has gotten by 6:31 p.m.: And finally, at 6:44 p.m., the floodwaters have engulfed tree trunks: Another viral video from the flooding was a 30-second time-lapse of the rapidly rising water on the Llano River in Kingsland, Texas. CNN posted the time-lapse to its TikTok, and people in the comments wasted no time connecting the little-to-no warning reportedly received by residents ahead of the flooding to President Donald Trump's gutting of government entities like the National Oceanic and Atmospheric Administration (NOAA), the National Weather Service (NWS), and FEMA. "if only we had a fully funded and supported national weather service..." someone wrote. This commenter pointed to DOGE's NOAA cuts, which resulted in thousands of laid off of staff, including scientists. This person wrote, "We should not have to beg for better warning systems." Someone mentioned how officials in hardest-hit Kerr County have been sounding the alarm on flood preparedness for nearly a decade. Someone else said that it's time for Texas to "come together as a community" in the face of Trump's hope to eliminate FEMA altogether. "But climate change doesn't exist," this person wrote, adding that rural Texas counties often vote against climate policy. And finally, this person wrote, "Officials just standing around watching the water rise" — literally and figuratively. What do you think? Discuss in the comments.

New topical threat may emerge near Southeast coast by mid-July
In a pattern similar to early July, an area along the southeastern coast of the United States is the zone being watched closely by AccuWeather meteorologists for the next round of tropical development in the Atlantic basin. Tropical depressions and storms tend to form close to Central America, the Caribbean and the waters adjacent to the southern U.S. early in the hurricane season. The area that gave birth to Chantal has been under close scrutiny by AccuWeather since the middle of June. The third tropical depression of the 2025 Atlantic hurricane season formed late on Independence Day afternoon, then went on to become Tropical Storm Chantal the next week. Chantal formed in response to a stalled front and a weak dip in the jet stream. Chantal moved inland earlier in the week and brought flooding rain to parts of the Carolinas. While conditions are likely to remain quiet in the tropical Atlantic for the next few days, the same zone along the southern Atlantic coast has a low chance of brewing another tropical depression or storm spanning July 14-17. Similar to what meteorologists were monitoring prior to Chantal's formation, development could take place over the northeastern Gulf instead. For the setup in mid-July, the front is weaker and the jet stream dip is not as pronounced as that of around Independence Day. However, wind shear (disruptive winds) may be a bit lighter compared to earlier in the month. Balancing the concerns out, there is a low chance of development. Should development take place on the Atlantic side of Florida, it may once again drift northward toward the U.S. coast. Should development occur on the Gulf side of Florida, steering breezes could guide the area of interest westward along the northern Gulf coast. •Have the app? Unlock AccuWeather Alerts™ with Premium+ In either case, showers and thunderstorms can increase in coastal areas and adjacent waters offshore even if a storm center fails to form. Should a center form, more substantial rain and wind, with building surf, would unfold. The next name on the list of tropical storms for the 2025 season is Dexter. Conditions remain too hostile for tropical development farther to the south from the western shores of Africa through the Caribbean through at least the middle of July. Vast areas of dry air, dust from the Sahara Desert and disruptive winds are the main factors against development. The 2025 Atlantic hurricane season is about one month ahead of the historical average, with three named storms already forming. Typically, the third tropical storm does not form until early August, or about a month after Chantal formed. The average date for the first hurricane is Aug. 11, and the first major (Category 3) hurricane generally forms around the start of September. AccuWeather's team of tropical meteorologists, led by hurricane expert Alex DaSilva, expects 13 to 18 tropical storms, of which seven to 10 will go on to become hurricanes and three to five are likely to evolve into major hurricanes for the 2025 season.

Houston weather: More rounds of rain Tuesday, marginal flood risk in Texas Hill Country
The Brief Shower Chances Possible in Hill Country Daily Round of Storms for Houston Area Tropics Quiet for Now HOUSTON - Prepare for another round of rain in the Houston-area and a warm afternoon in the 90s. There are no active Flood Watches in Hill Country as of this morning, but the Weather Prediction Center has outlined a 1/4 risk for isolated flooding in Central Texas today. Scattered downpours are possible through this evening for parts of the Texas Hill Country that have been ravaged by extreme flooding over the holiday weekend. Rivers are now well within their banks and, in fact, most are close to the pre-flood levels, but any more intense rainfall could cause levels to rise again. We are expecting a daily scattering of summer downpours in the greater Houston area today and tomorrow. Individual storms could drop a quick 1-2" of rain each day. Widespread flooding is not expected, but isolated street flooding is possible. Please be careful and avoid any flooded areas. Late this week, the coverage of rain will decrease Friday and temperatures could rise into the upper 90s before scattered storms return for the weekend. Chantal is now a post-tropical cyclone and moving into the Atlantic Ocean. Chantal was the first U.S. landfall of the year. Nothing else urgent is brewing in the tropics as of this evening and models aren't showing threats for Texas over the next several days. The Source Your Gulf Coast Weather Authority
