Ingredients in play for northwestern Ontario severe storms on Tuesday

![Northwestern Ontario storm risk map Tuesday]( With Ontario getting a break from the heat to start the week, but will return soon, northwestern sections of the province will be getting into the severe weather risk on Tuesday. In fact, multiple days of thunderstorms are expected in northern Ontario as a boundary stalls over the region. Tuesday could bring multiple rounds of thunderstorms into the region, with a severe chance for some areas. Folks can expect strong winds, heavy downpours and hail with any severe storm that forms. DON'T MISS: 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. Tuesday and Wednesday: Multiple storm opportunities An active weather boundary will move into northern Ontario on Tuesday, and stall over the coming days--bringing several opportunities for severe weather. SEE ALSO: From Tuesday morning to the lunch hour, forecasters will be watching a complex of storms stateside that could clip the Ontario-U.S. border. Strong winds and heavy downpours are the main threats with those storms. As the day progresses, later in the afternoon on Tuesday, storms could pop up from Dryden to Fort Hope, possibly becoming marginally severe with two-centimetre hail possible. If you are in the region, please stay on top of severe weather alerts and know what to do and where to go in the event severe weather approaches. On Wednesday, forecasters will then turn their attention to the potential for another cluster of storms to develop along the Lake Superior shores. Stretching from Marathon to Sault Ste. Marie, the risk will fall from the morning to early afternoon, then moving east of Sault Ste. Marie by the afternoon and evening time. There is some uncertainty on how much thunderstorm energy will develop and the severe potential at this time. But heavy rainfall and frequent lightning will be the main threats. There is still much uncertainty in the forecast Tuesday due to capping in the atmosphere and wildfire smoke, which could reduce the severe risk There is model uncertainty and trouble handling the location and movement of the thunderstorms stateside. Beyond, much cooler weather is expected late next week and well into the first week of August, especially in eastern areas. WATCH: In a tornado warning? Here's what you should do Stay with The Weather Network for more information and updates on your weather across northwestern Ontario.

Flooding across parts of Ireland after heavy rain

Orange-level weather warnings were in place for parts of Ireland on Monday morning after a night of heavy rain across the island. There were reports of localised flooding across parts of the island following a series of weather alerts on Sunday, with the unseasonably high rainfall into the start of the week. A status orange rain warning for Dublin, Louth, Meath and Wicklow came into effect from midnight and expires at 2pm on Monday. Warning Updates Status Orange Rain & thunderstorm warning for Dublin, Louth, Meath & Wicklow Valid: 00:00 21/07/25 to 14:00 21/07/25 Status Yellow Rain warning for Kildare & MonaghanValid: 00:00 21/07/25 to 14:00 21/07/25 Stay safe and updated⚠️ — Met Éireann (@MetEireann) July 20, 2025 Irish national forecasting agency Met Eireann said there would be persistent and heavy rain with a chance of thunderstorms. Meanwhile, Kildare is under a yellow-level rain warning for the same period. The warnings followed other alerts about thunderstorms in the east of the country and increased rain in the south-west. Met Eireann warned that the weather would bring widespread surface flooding, very difficult travelling conditions, lightning damage and very poor visibility in the worst-affected areas. The Met Office also issued a yellow-level rain warning for the east coast of Northern Ireland. Heavy rain over Northern Ireland on Monday morning with flooding possible in places. Some rain in parts of Scotland, northwest England and Wales too ⚠️ Heavy thundery downpours across southeast England and these developing in other eastern areas through the morning ⛈️ — Met Office (@metoffice) July 20, 2025 The region was expected to experience some of the worst of a heavy spell of rainfall until 6pm Monday. Forecasters predict affected areas could see half a month's worth of rain in less than a day after a warning was put in place for Antrim, Armagh and Down for the 24 hours from 6pm on Sunday. A more intense amber-level warning temporarily put in place overnight has since been lifted. The Met Office warned there is a risk that homes and businesses could be flooded. The expected rainfall carries a risk of flooding, power cuts and dangerous driving conditions. Forecasters also warn there is a small chance that some communities could be cut off by flooded roads while fast-flowing or deep floodwater could pose a danger to life. Simon Partridge, a forecaster with the UK Met Office, said: 'It looks like Northern Ireland is the place where we could see the most rainfall and certainly the most impactful rainfall. 'They could see 50 to 75mm of rain within 12 to 18 hours.' The region records an average of 89mm of rain in July, meaning more than half a month's rainfall could hit Northern Ireland in less than a day. A yellow-level thunderstorm warning was in place for the western half of Northern Ireland between midday and 8pm on Sunday. Flooding was already affecting routes in Fermanagh on Sunday evening, with the Marble Arch Road, Florencecourt, and Sligo Road, Enniskillen, both described as impassable by police. A PSNI spokeswoman said: 'Please take care when travelling, slow down, and exercise caution on affected roads.'

Weather latest: Britain braces for floods as thunderstorm warnings come into force

Britain braces for floods as thunderstorm warnings come into force Yellow and amber weather alerts have been issued across much of Britain. Thunderstorm warnings are in place in most of England, with only the southwest escaping a potential deluge today. The Met Office says there is a risk of sudden flooding, travel delays and power cuts. London is facing its first amber warning since January last year, with forecasters cautioning there could be "torrential" rain. The warning stretches from Hampshire to Kent and up to Cambridge, including all of London, until 11am. Between 20 and 30mm of rain could fall in one hour in the amber warning zone, rising to 60-90mm in just a few hours where heavy downpours persist. Some communities are "likely" to be cut off if roads flood and suffer cancellations to train and bus services, as well as power cuts, the Met Office said. While the rain is already hammering down in the capital, Scotland faces a yellow warning for rain from 4pm today until midday on Sunday. A separate yellow thunderstorm warning covers most of England and some parts of southern Scotland until 9pm. The southwest of England won't be spared for long, with a yellow rain warning in place from midday tomorrow until 3am on Monday.

Real-time flood alert sensors installed on Havelock North streams

Photo: LDR / Supplied Residents living near five Havelock North streams will have a real-time view of their water levels. Hastings Havelock North ward councillor Malcolm Dixon described the new water flow sensors as "wonderful progress". "The sensors monitor the level, flow and pressure of the streams and quickly put out alerts on rising water levels, allowing people to be prepared during weather events," Dixon said. "The sensors would be advantageous to everyone living in the area," he said. Thirteen of 15 planned monitors are in place, with the remaining two to be installed after bridge work on Joll Rd has been completed and an appropriate location has been confirmed on the Karituwhenua Stream. Once the project is complete, there will be three monitors on the Herehere, four on the Mangarau, three on Te Kahika, two on School, and three on the Karituwhenua streams. Joll Rd was flooded during Cyclone Gabrielle , due to a huge surge of water flowing through the nearby Mangarau Stream. More than 40 properties near the Mangarau Stream were placed in Category 2C after the cyclone. Earlier this month, the property owners were informed they had been recategorised as Category 1 - the lowest flood risk category, after almost two-and-a-half-years in limbo. In May, a report from Chief Ombudsman Peter Boshier chided the council, saying it had not acted for years despite concern from engineering consultants Stantec, which conducted annual checks of the dams, had noted failure of the dams would cause significant damage and could result in fatalities. Hastings Mayor Sandra Hazlehurst said the project was valuable for Havelock North residents, who could now be reassured that in severe weather, timely data would show the water levels on the streams. "The five streams all run through residential urban areas into the Karamū Stream, so we need near real-time information on what is happening. Hastings Mayor Sandra Hazlehurst. Photo: SUPPLIED "Council will monitor and be able to see trends over time to inform future planning and investment and monitor stream levels during heavy rain," she said. Council staff are monitoring the sensors and from September, once a process enabling the data to be fed through to the website is complete, residents will be able to access a dashboard to view the information. Council has partnered with Adroit Environmental Intelligence to install the real-time environmental monitoring sensors. Council's programme manager Darren de Klerk said the website dashboard will integrate water level data with local MetService information, and the Havelock North dam monitoring system, to provide a unified view for the council to monitor and residents to check. "We are excited about releasing this dashboard on our website. It will help build confidence within the community, with residents and other interested people able to keep an eye on stream levels," de Klerk said. Adroit general manager Guy Macpherson said the new high-tech monitoring system is the most comprehensive example of environmental sensors used for flood detection and emergency response in action in New Zealand, and is "likely to set the standard for other councils and regions".
