National Hurricane Center now watching 3 waves in Atlantic. Heat, storms expected Tuesday
The National Hurricane Center has been watching a disorganized area of showers and thunderstorms in the Atlantic associated with an area of low pressure hundreds of miles east-southeast of the Lesser Antilles, but the latest July 22 update gives it zero chance of further development.
"Environmental conditions are becoming increasingly unfavorable as the wave moves west-northwestward at around 15 mph, and further development is no longer anticipated," Hurricane Specialist Philippe Papin said in the update.
Most of the state can expect to see some rain and thunderstorms today from it, though, along with moisture from the Atlantic, National Weather Service forecasters said.
AccuWeather forecasters are watching the low-pressure system as well as an area of the Gulf of America where a slow-moving round of heavy rain and thunderstorms may develop this week, and an area extending from Texas to the Carolina coast with a low chance of tropical development.
The NHC is also tracking another tropical wave that just left the coast of Africa, making that three to watch in the Atlantic.

Florida heat wave lessening on paper, still feels hot
Meanwhile, the oppressive heat across Florida is letting up a bit as the heat dome bringing record temperatures to the South expands across the Central Plains and Midwest, National Weather Service forecasters said.
Heat advisories for July 22 have been issued for North Florida, the Panhandle, and North Central Florida, with heat index values expected up to 110-111 with a few spots in the Panhandle facing major heat risks, but the rest of the state is forecast to see temperatures "just" in the high 80s and low 90s and heat index values up to 100-105.

When is the Atlantic hurricane season?
The Atlantic hurricane season runs from June 1 through Nov. 30.
Ninety-seven percent of tropical cyclone activity occurs during this time period, NOAA said.
The Atlantic basin includes the northern Atlantic Ocean, Caribbean Sea and Gulf of America, as the Gulf of Mexico is now known in the U.S. per an order from President Trump. NOAA and the National Hurricane Center are now using Gulf of America on its maps and in its advisories.

Why does NHC say 'tropical cyclone' on its maps instead of hurricane or tropical storm?
Tropical cyclone is the generic term used by the National Weather Service, NOAA and the National Hurricane Center for any tropical system, even if it's in the tropical Atlantic basin.
To be more precise, a tropical cyclone is a "rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has closed, low-level circulation," NOAA sadi.
Once maximum sustained winds reach 74 mph, what it is called is determined by where it originated:
: for storms in the North Atlantic, central North Pacific, and eastern North Pacific.
: for storms in the Northwest Pacific.
: for storms in the South Pacific and Indian Ocean.

Map Shows Heavy Rain as Flash Floods Hit Three States
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 flash flood warnings for parts of Iowa, Illinois and Missouri, as thunderstorms in the region bring heavy, rapid rainfall. Why It Matters Flooding is the second deadliest weather hazard nationwide, with most fatalities occurring when vehicles are swept away by rising waters. On July 4, Texas flash floods killed at least 135 with three still missing. As of mid-July, the NWS has issued a record number of flash flood warnings year-to-date, with 3,160 warnings issued through July 16, according to Iowa State University's Iowa Environmental Mesonet tracker. What To Know In a Saturday advisory, the NWS warned that portions of the three states are under flash flood warnings due to expected thunderstorms that will bring heavy rain. As of Saturday morning, "between 2 and 5 inches of rain have fallen," and the "expected rainfall rate is 0.25 to 1 inch in 1 hour." For parts of southeastern Iowa, west central Illinois, and northeastern Missouri flash flooding is already occurring, the NWS warned. Missouri Department of Transportation reported that portions of some roads have been closed due to water on the roadways. NWS warned people to "turn around, don't drown when encountering flooded roads," noting that "most flood deaths occur in vehicles." Nearly half of Iowa is also under extreme heat watch on Saturday, as July continues to bake the area with frequent heat indexes into the triple digits. Heat index values reflect how hot it feels when both temperature and humidity are factored in. What People Are Saying NWS Des Moines wrote in a Friday X, formerly Twitter, post: "Dangerous heat & humidity builds across Iowa through early next week. Maximum heat index values are expected to exceed 100 degrees everywhere, with a few locations potentially exceeding 110F! An Extreme Heat Watch has been issued for western/central Iowa beginning Sunday." AccuWeather meteorologist Alex DaSilva previously told Newsweek: "When the atmosphere is getting warmer as a what it's doing is making summer warmer and the shoulder seasons warmer as well. What's happening is those seasons, especially in the summertime, the [atmosphere's] ability to hold more moisture is going up as well. It doesn't guarantee we will see more rain over a certain area, it rains, it's going to rain heavier." Michael Lowry, hurricane specialist and storm expert, wrote in a July 15 X post: "So far in 2025, more flood warnings have been issued by @NWS than any year on record (since 1986)." AccuWeather chief meteorologist Jon Porter said in a July 21 AccuWeather article: "So far in 2025 across the U.S., there's been a 70% increase in reports of flash flooding when you compare that to the 10-year historic average through mid-July." What Happens Next? Many of the flash flood advisories are until 11:30 a.m. local time.

Chicago weather: Flood Watch still in effect for much of the area, more showers coming
CHICAGO - As of this writing, there is very little rainfall of any kind in Chicagoland. During the day, because of the tropical air mass in place, showers and thunderstorms can form at just about any time. Fox 32 Meteorologist Mike Caplan has the forecast. What to Expect A Flood Watch is in effect through the evening for most of the viewing area. The watch for Lake and McHenry counties was canceled by the National Weather Service. If all one does is look at that map, it makes it appear as though the entire area will be flooded. That is far from the case. Instead, only small portions of Chicagoland might get excessive rainfall at some point today. There will be many more areas that do not receive very much rainfall. The risk of severe thunderstorms with damaging winds exists, especially during the afternoon hours. But once again, those will likely be limited in coverage. Highs today will be held down because of cloud cover and occasional rain. Most will stay in the low 80s like yesterday. What's next Intense heat builds back into the area for three days starting tomorrow. Highs should reach the low 90s on Sunday, mid to upper 90s on Monday, and low 90s on Tuesday. While a spotty shower or thunderstorm cannot be completely ruled out during the heat wave, it is more likely it will remain dry for the majority of our viewing area. A higher chance of showers and thunderstorms arrives Tuesday night and Wednesday with a front that will knock temperatures and humidity levels down noticeably starting Wednesday and continuing through the end of the work week.

Severe thunderstorm watch issued in West Michigan
GRAND RAPIDS, Mich. (WOOD) — Strong to severe thunderstorms are expected for parts of West Michigan this evening. Inside Radar A severe thunderstorm watch has been issued for Ottawa, Kent and Ionia counties south until 10 p.m. Thursday. Damaging winds are the primary concern with any storms that develop. Most of West Michigan has been placed in a level 2 out of 5 severe risk by the Storm Prediction Center through Thursday night. A cold front will slowly advance into a very hot and humid environment, making it easy for storms to erupt quickly. Upper-level wind support is quite weak. As a result, storms will move slowly and severe storms will have a short lifespan. The cold front will take its time moving through the state, and may even produce rain early Friday morning south of I-96. Download the free Storm Team 8 weather app TIME FRAME FOR SEVERE STORMS The most likely time frame for severe weather to happen would be between 6 p.m. Thursday and midnight, before storms transition to nonsevere. Sign up for the Storm Team 8 daily forecast newsletter Another system is expected to move into West Michigan Saturday, with a good chance of heavy rain for the entire area. Severe chances for that day are low at this time. Stay with for updates. Copyright 2025 Nexstar Media, Inc. All rights reserved.
