National Hurricane Center now watching 3 waves in Atlantic. Heat, storms expected Tuesday

Yahoo5 days ago
The latest maybe-threat in the tropics is currently no threat at all.
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.

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.

Los Angeles County canine rescue teams return after aiding Texas flood recovery

Canine rescue teams from Los Angeles County returned to the Southland on Sunday morning after spending more than two weeks assisting with search and recovery efforts in Central Texas following the devastating floods in the region. The team with the Los Angeles County Fire Department was deployed to Texas on July 8. Over the next 18 days, the specialized dogs helped rescue teams search for remaining victims after floods tore through the region, leaving at least 138 dead. Dozens are still unaccounted for. "All canine teams and first responders are to be commended for their steadfast commitment in assisting with the search and recovery efforts in central Texas," said County of Los Angeles Fire Chief Anthony C. Marrone. "We continue to stand alongside the residents and communities impacted by the devastating flooding and pray for continued strength and resilience." Gov. Gavin Newsom deployed the team, along with other teams from Oakland, Sacramento, Menlo Park, Orange County, and Riverside County. At LAX on Sunday morning, crewmembers told CBS News Los Angeles that it worked in excruciating heat with high humidity, which California-based crews are not used to. "It was very challenging compared to our other deployments," said Capt. Celina Serrano. "We did have to deal with something unexpected, with the humidity, which is what we're not used to out here." Serrano added that the dogs' work schedules had to be altered due to the weather conditions. A canine, Prentiss, had to have emergency surgery while in Texas but is expected to make a full recovery. He's going to have a two-month break from his duties before authorities assess whether he should return to work.

Severe weather likely on Sunday, one or two tornadoes possible

Severe thunderstorms are likely across portions of southern Manitoba and northwestern Ontario again on Sunday as an active pattern remains in place to close out the weekend. Several rounds of thunderstorms are possible—one in the morning, followed by another in the mid-afternoon to early evening hours. One or two tornadoes are possible. Keep an eye on the radar and stay aware of watches and warnings in your area. Know where to go and what to do if a tornado warning is issued for your location. READ NOW: Severe weather likely on Sunday Sunday will kick off with an early-morning mesoscale convective system (MCS) expected to develop stateside. This organized line of thunderstorms will push into northwestern Ontario and head toward the Thunder Bay area. Expect this first round of storms between 8:00 a.m. and 12:00 p.m. local time. DON'T MISS: A second line of severe thunderstorms will develop and approach the area during the afternoon hours. Large hail, gusty winds, heavy rainfall, and one or two tornadoes are possible in these storms. The environment is favourable for rotating thunderstorms near the international border, including Fort Frances and Atikokan. STAY SAFE: There remains some uncertainty in the timing and coverage of the lines of storms in northwestern Ontario, as they depend on the timing of the cold front's arrival and the atmosphere's ability to destabilize itself amid the wildfire smoke over the region. Folks across southern Manitoba, including Winnipeg, could see severe thunderstorms fire up beginning Sunday afternoon as a low-pressure system moves into the region. The main hazard from this cluster of storms will be large hail and heavy rainfall. Stay with The Weather Network for all the latest on this evolving severe weather threat.

Bryan Norcross: We'll likely have an Atlantic disturbance to follow next week

Computer forecasts continue to indicate that a fairly robust disturbance will move off Africa about Monday. The track is forecast to be far enough south that it won't immediately plow into the Saharan dust. There is a reasonable consensus in the various long-range models that the disturbance will track across the Atlantic and be in the vicinity of the northeast Caribbean late in the week. None of the current projections shows a storm of any significance when the system is near the Caribbean. It will have run a gauntlet of intruding Saharan dust, dry air, and only marginally conducive upper-level winds on its trek west. If it survives with some sort of circulation intact late in the week, there is some evidence that the overall atmospheric pattern will become more conducive for storm development. The long-range computer forecasts that predict an organized system forming—both the traditional forecasts and the new AI models—generally show a track curving near or east of the Bahamas and off the East Coast of the U.S. The odds of this happening are still in the low range, but the possibility is interesting because this is the first time that long-range projections have shown a disturbance getting far enough across the Atlantic to potentially develop into a storm. We'll see what happens over the next several days. Remember, the rule: Forecasts for systems that are just developing or are disorganized are subject to larger errors and will often change. This system hasn't even emerged from the African coast, so there's a long way to go. The National Hurricane Center is not predicting any development over the next 7 days, so we're talking about more than a week from now before anything might happen. The National Hurricane Center has three areas to watch in the eastern Pacific. Each one has a decent chance of developing into at least a tropical depression, and computer model forecasts indicate a good chance they'll evolve into named storms. Two of the systems look to track south of Hawaii, and the third, parallel to the Mexican coast. Over the next few weeks, a number of computer forecasts are predicting multiple eastern Pacific storms. The possible tie to Atlantic storm development is related to the phenomenon called the MJO. The MJO is a large-scale pulse that slowly revolves around the Earth, alternately suppressing and enhancing storm development. Over the next week or so, forecasts predict that the enhancing phase will cross the eastern Pacific. This might be responsible for the predicted outbreak of organized storms. If the MJO pulse continues moving east as predicted, it would move over the Atlantic from west to east through the first part of August. This would, broadly speaking, make the atmospheric pattern across the tropics more conducive for development. This MJO forecast adds a little credence to the idea that the Atlantic disturbance might be more inclined to develop a week or 10 days from now. None of this is surprising, of course. On average, the odds of storm development increase in August and dramatically increase after August 15. The disturbance we watched track across the northern Gulf has died out, but the moisture lingers from Mississippi to East Texas. Tropical downpours causing local flooding are still possible. Stay aware. The moisture should move out after the weekend, but extreme heat will move in. The combination of heat and humidity will likely push the feels-like temperature into the 110°F range.
