Iona becomes first hurricane in central Pacific Ocean this year
A tropical storm in the central Pacific Ocean rapidly strengthened into Hurricane Iona on Monday, forecasters said. The hurricane didn't pose an immediate threat to the Hawaiian Islands. As of early Monday morning in Hawaii, Iona was located about 895 miles southeast of Honolulu, according to the National Hurricane Center based in Miami. Iona was expected to move westward for the next couple of days, forecasters with the hurricane center said. "Confidence remains high that Iona will stay well south of the Hawaiian Islands," forecasters said. The storm was a Category 1 hurricane and it is expected to strengthen. By Tuesday, Iona's maximum sustained wind speeds were forecast to be at Category 2 strength. The storm was then expected to gradually weaken during the week. Iona initially formed as a tropical depression late Saturday night, forecasters said. As the depression gained strength, it turned into the first named storm in the central Pacific Ocean this season. The eastern Pacific has seen several named storms so far this season. Last month, Erick made landfall in Mexico as a Category 3 hurricane. Earlier this month, Flossie also reached Category 3 strength as it skirted up the Mexican coast, but ultimately didn't make landfall. Barbara, this season's first hurricane in the eastern Pacific, reached Category 1 strength off Mexico's coast, and also didn't make landfall. The Atlantic Ocean has seen three named tropical storms so far this year. Forecasters at Colorado State University expect the Atlantic season to be above average with 16 named storms, eight of which are expected to be hurricanes.

Smoke set to return as hazardous heat settles over Ontario
Summertime remains firmly in control for the closing days of July as muggy heat blankets portions of Ontario for the next several days. Heat warnings are in effect as the dangerous combination of high heat and excess humidity could lead to heat-related illnesses in short order. Forecasters are also monitoring the potential return of smoky conditions across parts of southern Ontario to start the new workweek. DON'T MISS: Dangerous heat persists for several days in spots We're in the midst of Ontario's fifth multi-day heat event of the season. Daytime high temperatures will hover between 30 and 34 degrees on Monday, with feels-like values ticking toward 40 when you factor in the excessive mugginess. The humidity will prevent nighttime temperatures from dropping below 20 degrees in many locations, preventing any meaningful heat relief after sunset. Smoke and haze may keep daytime temperatures a tad lower in some locations, depending on their concentration. Heat affects everyone. Vulnerable people are especially susceptible to heat-related illnesses, including those with chronic health conditions and folks living without air conditioning. Be sure to check on your elderly family, friends, and neighbours. A cold front pushing into Ontario will lower temperatures in a hurry as the week progresses. Central Ontario could see temperatures fall by Monday night, while the heat will persist until Wednesday across southern Ontario until the boundary slides south across the region. Warmest July since 2020 This is shaping up to be the warmest July in five years for many cities in southern Ontario. Toronto-Pearson has seen an average high temperature this month of 29.2°C, with Ottawa clocking in with an average of 27.9°C. RELATED: Mean temperatures—averaging together the day's high and low—above 24°C have become more common in recent decades for Toronto. Since 1999, the city has seen six Julys with temperatures above that threshold. Before that, the city only experienced that level of heat once in 1955. Smoke set to return to portions of Ontario Wildfires continue to burn on the Prairies and in the western United States. Various smoke models indicate that thick smoke and haze will spread across eastern Ontario, including Ottawa, by Monday morning. Folks across northwestern Ontario will experience increased smoke concentrations on Monday, and fine particulate matter is expected to cover most of the province and linger into Tuesday. If you're sensitive to smoke, plan ahead for any disruptions to outdoor activities to start the week. Header image created using graphics and imagery from Canva.

Colorado heat wave expected for several more days before cooldown
The heat impacting Colorado will continue for two more days before some slight relief arrives on Tuesday. Sunday will top out in the upper 90s across the Front Range. The record for the day is 98 degrees, set back in 1964. Monday could be another day of record-tying or breaking heat. The current record is 100 degrees. Several towns and cities on the Eastern Plains are expected to see triple-digit heat both Sunday and Monday. Tuesday, some slight relief arrives, and temperatures will return to normal for this time of year. Overnight Tuesday, a front will drop into the state, dropping temperatures into the 80s and upper 70s. The biggest change we will see is rain showers across the state. Some of the rain could be heavy at times, and localized flooding is possible. The rain is highly needed for the western half of the state, where high fire danger and drought continue.

Stormy Saturday interrupts southern Ontario's weekend
Ontario won't catch a break from the active weather to kick off this final weekend of July as forecasters look at multiple zones across the province for renewed storm development. Folks in southern Ontario will see multiple opportunities for thunderstorms during the day Saturday, a few of which could approach severe limits. PHOTOS: Southern Ontario storms arrive in two rounds Saturday will start with a weak low-pressure system slowly nudging into Ontario from Michigan, though a strong centre of high pressure over Quebec won't allow the low to advance very far. A stationary boundary associated with that low-pressure system will slide into southwestern Ontario through the early afternoon hours, potentially triggering some non-severe thunderstorms across the region. SEE ALSO: Later in the day, an approaching cold front will help trigger a second round of storms across southern Ontario. This second round will have a higher severe risk between Windsor and Kincardine due to greater instability present in the atmosphere. The possibility of severe weather depends on the timing of the cold front. Some models are suggesting that the severe storms could arrive in the late evening into the overnight period.
