More showers and thunderstorms Monday, with highs of 27 C by Wednesday
In what has become a familiar weather story, persistent rain fell over the Calgary area overnight, intensifying to scattered thunderstorms by the Monday morning commute. More rain will populate along the foothills throughout the day before tracking west to east across southern Alberta. Calgary can expect intermittent showers and thunderstorms until the late evening when a steering low-pressure system in east-central Alberta moves into Saskatchewan. More showers and thunderstorms Monday, with highs of 27 C by Wednesday Communities in southern Alberta could see some more intense thunderstorms on Monday as they sit closer to a warmer air mass and may experience the ill-effects of the collision of that warmer air when it encounters the northern colder air mass. Starting Tuesday, a dominant ridge of high pressure riding the northern states will move into Alberta and provide a few days of warmer temperatures with more stable conditions. Monday's high in Calgary will be five degrees below seasonal, with Wednesday's high forecast to sit four degrees above seasonal. More showers and thunderstorms Monday, with highs of 27 C by Wednesday The daily high temperatures for the long weekend should be just below seasonal in Calgary with a chance of showers on Friday and Saturday. The overnight lows over that same period are expected to sit just above seasonal.

Sydney, Melbourne, Brisbane weather: Huge 4,000km rain band set to drench millions of Australians this week
Up to three-quarters of Australia's population will be drenched by a 4,000km rain band this week as a low-pressure system hurtles towards the east coast. The tropical low and associated cold front is due to cross the southeast on Tuesday, after sending temperatures plunging in South Australia on Monday. Forecasters say millions from Tasmania all the way up to the Cape York Peninsula will be soaked by the enormous rain band this week. The low is expected to deliver a 'decent amount of rain' to every state and territory in Australia between now and the weekend, according to Weatherzone. Forecasters say large parts of New South Wales and Queensland will be drenched, with powerful winds to impact SA, Victoria and Tasmania. Predictions of widespread falls between 10mm and 40mm in central Queensland and NSW are forecast between Friday and Monday. Central Queensland could record up to 100mm of rain, with Brisbane and Townsville, in the state's far north, also receiving a rare soaking. The Victorian SES has advised people to make adequate preparations ahead of the powerful winds and take precautions while driving. Damaging wind gusts are expected to average from 65 to 90km/hour, with peak gusts of 125km/hour in elevated areas such as Falls Creek and Mount Hotham. Blizzards have also been tipped in the state's alpine regions. A second low pressure system is expected to bring widespread rain across the eastern half of Australia between Friday and Sunday. The rain will be 'heavier and more widespread' than the current system due to the influence of a large northwest cloud band, Weatherzone said. Perth shivered through a 3.2C morning on Tuesday, five degrees below its July average. Other regions saw temperatures fall to record lows, including a maximum temperature of 13.9C at Red Rocks Point, its lowest in six years. Another cold burst will follow in WA's capital on Wednesday going into Thursday. Perth Wednesday: Showers. Possible storm .Min 8C. Max 17C. Thursday: Showers easing. Min 5C. Max 14C.

Potential Tropical Storm Dexter may bring 'impactful' rain from Houston to Panama City
A broad area of low pressure continues to move westward across the Florida Panhandle and is producing disorganized showers and thunderstorm activity mainly south of its center, the National Hurricane Center said early Wednesday morning. Hurricane center forecasters said the system, designated as Invest 93L, is forecast to continue moving westward and could emerge or redevelop over the far northeastern to north-central portion of the Gulf, reaching the coast of Louisiana by Thursday. "If this system moves far enough offshore, environmental conditions over the Gulf appear generally favorable for additional development, and a tropical depression could still form over the next couple of days before the system moves fully inland by the end of the week," the hurricane center said in an advisory early Wednesday. 'Impactful' rain from Texas to Florida Even if the system doesn't develop into a named storm, which would be named Dexter, forecasters warn it will still bring significant impacts. AccuWeather forecasters expect a potential tropical depression to make landfall in southeastern Louisiana on Thursday afternoon, bringing heavy rain, storm surge of 1 to 3 feet, and wind gusts of 40 to 60 mph. Coastal Mississippi could also be affected, especially if the system strengthens into a tropical storm before landfall. Meteorologist Nick Lilja said in a Facebook post that, regardless of whether the system develops or where it tracks, heavy rainfall is expected. "If you live anywhere between Galveston and Panama City and within 50 miles of the coast, I'd make certain your property is clear and clean and that water can easily exit your property and get to the drainage areas," he wrote in a post Sunday. In a separate post Tuesday, Lilja said forecast models are beginning to converge on southeast Louisiana and the Mississippi coast for the highest rainfall totals. Still, he warned that the entire stretch from Morgan City, Louisiana, to Panama City, Florida, is 'fair game for at least a 48-hour period of a washout between Wednesday and Sunday as this thing meanders west." Will a tropical system hit Texas? While Texas is not currently in the projected path, remnant moisture drifting west or southwest across the Gulf could trigger scattered storms — especially in Southeast Texas along the coast. The National Weather Service in Houston has issued a slight risk of excessive rainfall for areas east of I-45 on Friday. 'A surge of tropical moisture could bring showers and thunderstorms to Southeast Texas later this week,' the agency wrote. 'This heavy rainfall threat will greatly depend on how a disturbance over Florida evolves over the next several days.' Atlantic storm tracker This forecast track shows the most likely path of the center of the storm. 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. What is a 'homegrown' system? A "homegrown" or "homebrew" storm is one that forms close to the U.S. coast, often in the Gulf of Mexico, the western Caribbean, or the nearby Atlantic. These storms are more common during the early part of the hurricane season, which runs from June 1 to Nov. 30, according to an online forecast discussion from AccuWeather. While Cape Verde hurricanes — which form from tropical waves off the coast of Africa — account for about 85% of major hurricanes and 60% of all tropical storms and hurricanes, most of these storms stay out to sea or weaken before reaching the mainland U.S. They can be extremely powerful when they do make landfall, but that's relatively rare. In fact, only eight out of 54 hurricanes that struck the U.S. between 1995 and 2023 originated as Cape Verde systems, according to storm track data. These so-called "homegrown" storms tend to form or intensify quickly in warm, shallow waters near the coast, leaving little time for preparation. Because of their proximity, they're often considered the greater threat to the U.S., even if they're shorter-lived or not as strong as Cape Verde storms.

Storm tracker: System continues to move across Florida toward the Gulf
A broad area of low pressure continues to move westward across the Florida Panhandle and is producing disorganized showers and thunderstorm activity mainly south of its center, the National Hurricane Center said early Wednesday morning, July 16. Hurricane center forecasters said the system, designated as Invest 93L, is forecast to continue moving westward and could emerge or redevelop over the far northeastern to north-central portion of the Gulf, reaching the coast of Louisiana by Thursday. "If this system moves far enough offshore, environmental conditions over the Gulf appear generally favorable for additional development, and a tropical depression could still form over the next couple of days before the system moves fully inland by the end of the week," the hurricane center said in its 2 a.m. ET advisory on July 16. The system is expected to provide heavy rainfall, which could produce localized flash flooding over portions of Florida through Wednesday. Flash flooding could also occur in portions of the north-central Gulf Coast beginning late Wednesday and continuing through Friday, the hurricane center said. AccuWeather forecasters expect a potential tropical depression to make landfall in southeastern Louisiana Thursday afternoon, bringing heavy rain and storm surge. Storm surge of 1 to 3 feet and wind gusts from 40 to 60 mph are possible in southeastern Louisiana to coastal Mississippi, according to AccuWeather, especially if the storm organizes into a tropical storm before landfall. Invest 93L currently has a 40% chance for tropical development over the next seven days and a 40% chance over the next 48 hours. The next named storm of the 2025 Atlantic hurricane season will be Dexter.

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. Illustrations include an array of forecast tools and models, and not all are created equal. The hurricane center uses only the top four or five highest performing models to help make its forecasts. 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. 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. Develop an evacuation plan: If you are at risk from hurricanes, you need an evacuation plan. Now is the time to begin planning where you would go and how you would get there. Assemble disaster supplies: Whether you're evacuating or sheltering-in-place, you're going to need supplies not just to get through the storm but for the potentially lengthy aftermath, NOAA said. Get an insurance checkup and document your possessions: Contact your insurance company or agent now and ask for an insurance check-up to make sure you have enough insurance to repair or even replace your home and/or belongings. Remember, home and renters insurance doesn't cover flooding, so you'll need a separate policy for it. Flood insurance is available through your company, agent, or the National Flood Insurance Program. Act now, as flood insurance requires a 30-day waiting period. Create a family communication plan: NOAA said to take the time now to write down your hurricane plan, and share it with your family. Determine family meeting places, and make sure to include an out-of-town location in case of evacuation. Strengthen your home: Now is the time to improve your home's ability to withstand hurricane impacts. Trim trees; install storm shutters, accordion shutters, and/or impact glass; seal outside wall openings. Gabe Hauari is a national trending news reporter at USA TODAY.
