Is Atlantic hurricane season behind schedule? Here's what's really going on
Andrea kicked off the season on June 24, with Barry following on June 29, both lasting less than a day. The National Hurricane Center has flagged an area for possible development over Florida, but regardless of whether this system is named, it will be a prolific rainmaker for the peninsula.
The Eastern Pacific, on the other hand, has been bubbling. Hurricane Flossie — the basin's sixth named storm this season — is expected to sideswipe southwest Mexico this week with flood and mudslide potential.
There's a balancing act at play when tropical systems develop. While ocean temperatures in the Atlantic are warm enough to fuel hurricanes, disruptive winds are quickly tearing apart the seedling storms. Saharan dust plumes are also inhibiting hurricane formation by wrapping dry air into storms. Weather models, which take into account several factors, give no solid indications that well-organized, long-lasting storms could develop through mid-July.
In short: yes. July tends to be more of a waiting month during hurricane season. On average, only one named storm forms in July, and this year may feel especially slow because the storms that have been named were very short-lived. Both the Atlantic and Eastern Pacific basins should be relatively quiet well into July, according to the Climate Prediction Center.
But storms could still spin to life this month, and if any do, they have potential to be particularly dangerous. July storms in the Atlantic tend to develop in the shallow Caribbean or Gulf waters, which are warmer this time of year than other, deeper parts of the ocean.
This can fuel rapid intensification and quick landfall, amping up the threat due to short warning lead times. Human-caused climate change is causing hurricanes to produce heavier rainfall and intensify more rapidly than in previous decades.
As we move into August, attention shifts to what forecasters call the 'main development region' — a vast swath of ocean from the west coast of Africa across the central tropical Atlantic. That area usually spawns late-season storms, and it's where some of the strongest hurricanes originate.
Atlantic hurricane season peaks in mid-September. This season, the National Oceanic and Atmospheric Administration is predicting 13 to 19 named storms, six to 10 of which will become hurricanes, and 3 to 5 of these could reach major hurricane intensity of Category 3 or stronger. The agency said they are 70% confident in this particular outlook.
Forecasters are used to dealing with uncertainty, but a new type of unpredictability is brewing this season.
A crucial source of satellite data that hurricane forecasters use monitor changes in storm intensity is expected to be shut down at the end of July, reportedly due to cybersecurity concerns. NOAA was blindsided by this announcement, CNN reported, though the agency has publicly maintained there are many other data sources that will allow for accurate forecasts this season.
The timing raises concerns, as the most active part of hurricane season takes place after July. As hurricane expert Michael Lowry noted on social media, 'The whole thing raises more questions than it answers. The satellites work. Why not keep the data flowing to scientists who use it to forecast the deadliest storms on earth?'
This blow is dealt just as forecasters have also lost access to the fleet of drone boats that provided continuous, direct observations from below storms, and in the wake of staffing cuts throughout the agency.
In 2025, when meteorologists know more about hurricane forecasting than ever before, forecasters may be heading into the most dangerous hurricane months with a critical blind spot.

Tornado, damaging wind risk in Ontario and Quebec; prepare in case of outages
Heat and humidity return to Central Canada, elevating the thunderstorm risk in both Ontario and Quebec Thursday. DON'T MISS: Several lines of severe thunderstorms are expected to develop as humidity and instability peak during the afternoon and evening hours. Key factors driving this weather include moisture, instability, wind shear, and a low pressure system acting as a trigger. While the main risks are hail, heavy downpours and potent, potentially damaging wind gusts, there is a chance of rotation and one or two tornadoes for parts of northeastern Ontario, Lake Huron-Georgian Bay shores and Quebec. Make sure you keep an eye on the radar––especially if you have outdoor plans––and stay aware of any severe weather watches or warnings issued in your area. Thursday: Severe storm threat bubbles up with the rising humidity and instability Southern and eastern Ontario will experience humidex values near 40°C during the afternoon, with dry conditions likely until storms develop in the evening hours. SEE ALSO: Timing: 4-5 p.m. Thunderstorm activity is expected to begin as early as 4–5 p.m. in northeastern Ontario and parts of Quebec, where severe weather has the highest confidence. Early-stage storm development may lead to isolated, rotating cells capable of producing tornadoes, particularly in Quebec. Heavy rainfall is also a significant risk, with totals exceeding 50 mm locally due to multiple storm cells passing over the same areas. Localized flooding is a concern. RELATED: 7-8 p.m. As storms mature, a transition to a more linear pattern is expected, increasing the likelihood of damaging wind gusts between 90–100+ km/h, particularly along Georgian Bay and Lake Huron Shores from 7–8 p.m. onwards. Late evening and overnight: Thunderstorms may reach the northern Greater Toronto Area (GTA) during the late evening or overnight hours, but will weaken as energy diminishes. DON'T MISS: Rainy periods could persist into Friday morning for parts of the GTA. WATCH: In a tornado warning? Here's what you should do Click here to view the video Signs of cooler weather for the August long weekend Early next week, conditions will stay mostly sunny, hot, and humid, accompanied by a chance of passing thunderstorms. A strong cold front is expected to sweep south through the region midweek, bringing a heightened risk of thunderstorms. By late next week, cooler air will settle in, with temperatures expected to remain below seasonal averages through the August long weekend and into the first week of the month. However, a return to significantly warmer weather is anticipated for the second week of August.

Drier air moves in after round of scattered showers across South Florida
Scattered showers and storms will move across South Florida on Thursday before drier air moves in just in time for the weekend. The chance of rain will be highest in the morning through the midday hours, with the potential for some heavy downpours and localized flooding. The atmosphere remains juicy and unstable due to an upper-level area of low pressure which has led to all the wet weather over the last few days. Afternoon highs will climb to the low 90s, but when the humidity is factored in, it will feel like the upper 90s and 100s. There is a moderate risk of rip currents along the Atlantic beaches and the UV index is extreme. There are no alerts or advisories for boaters over the Atlantic or Keys waters. Late Thursday afternoon, a plume of Saharan dust will begin to move and storms will push inland and to the west. The drier air and high pressure will bring drier, hotter conditions on Friday and through the weekend. It will be a scorcher due to the lack of rain and cloud coverage. Highs will soar to the low 90s and it will feel like the triple-digits. The National Weather Service may issue heat advisories. Early to middle of next week the chance of rain rises with the potential for passing showers and a few storms. The National Hurricane Center is monitoring a trough of low pressure over the north-central Gulf that has a low potential (10% chance) of development as it moves generally westward across the north-central portion of the Gulf. Regardless of development, this system is expected to bring heavy rain and the potential for flooding along the Gulf coast.

Storm tracker: System in the Gulf could bring heavy rain to several states
Much of Florida and portions of the northern Gulf Coast could see heavy rainfall Thursday due to an area of low pressure currently located over the northeastern Gulf. The National Hurricane Center said in a July 24 advisory the area of low pressure is "currently producing a broad area of disorganized showers and thunderstorms." Forecasters said the system is forecast to move generally westward across the north-central and northeastern portion of the Gulf over the next day or two where some slow development is possible. By the weekend, the system is expected to move inland, ending its chances for development. "Regardless or tropical cyclone formation, locally heavy rainfall is possible for portions of the northern Gulf coast through this weekend," the hurricane center said in the advisory. Hurricane center forecasters give this system a 10% chance of formation through the next seven days. The National Weather Service said the heavy rain potential is expected to move west towards Texas on Friday, with additional downpours likely along the Gulf Coast. NHC also tracking another system in the Pacific The NHC also said in its July 24 advisory it is keeping an eye on another area of low pressure that is expected to form well southeast of the Hawaiian Islands this weekend. Hurricane center forecasters said some gradual development is possible thereafter while the system moves generally westward. The system has a 30% chance of formation through the next seven days, according to the NHC.

It does not illustrate the full width of the storm or its impacts, and the center of the storm is likely to travel outside the cone up to 33% of the time. 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.
