NOAA Hurricane Center tracks tropical disturbance in Atlantic
A tropical wave interacting with a broad area of low pressure is producing disorganized showers and thunderstorms about 900 miles west-southwest of the Cabo Verde Islands, forecasters said in their 8 a.m. Tropical Weather Outlook.
Environmental conditions are marginally conducive for gradual development of this system during the next few days, as it moves westward to west-northwestward around 10 mph. By the middle of next week, environmental conditions are forecast to become unfavorable for further development.
What do the colored, hatched areas on the NOAA map mean?
The hatched areas on the National Hurricane Center's tropical outlook map indicate "areas where a tropical cyclone — which could be a tropical depression, tropical storm or hurricane — could develop," said National Hurricane Center Deputy Director Jamie Rhome.
The colors make it visibly clear how likely a system could develop, with yellow being low, orange medium, and red high.
The National Hurricane Center generally doesn't issue tropical advisories until there is a named storm, but there is an exception.
"If a system is near land and there is potential for development, the National Hurricane Center won't wait before it issues advisories, even if the system hasn't become an actual storm. This gives residents time to prepare," Rhome said.

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.

North Texas is under its first heat advisory of the summer. Temperatures on Thursday could stay in the upper 90s but the heat index will bring "feels-like" temperatures to 105 degrees. A First Alert Weather Day is in effect due to the heat advisory. Expect the same forecast on Friday. A First Alert Weather Day was also issued for Friday due to the heat and likelihood of another heat advisory. By Saturday, clouds and humidity will increase, bringing the temperature down a little bit. The higher humidity on Saturday and Sunday will bring the "feels-like" temperatures to the same as today. The seven-day forecast shows the summer heat is in full swing. A heat advisory is issued for dangerous heat conditions that are not expected to reach warning criteria, according to the National Weather Service. When there is a heat advisory, consider postponing or rescheduling outdoor activities, especially during the heat of the day. When outside in the heat, take frequent water and shade breaks.

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.
