Tornado risk for the Ottawa area Thursday
Environment Canada has issued a severe thunderstorm watch west of Gatineau Thursday, noting a tornado could develop. The watch covers Quyon and communities to its north and west. Forecasters mention strong gusts of wind, large hail and heavy rain along with lightning, but do not yet say when. Environment Canada has also been mentioning possible Thursday tornadoes for eastern Ontario since Tuesday. There are no weather alerts there yet. Environment Canada recommends staying indoors and taking cover in a basement where possible during these types of threatening weather, and notes strong winds can damage trees or buildings and overturn vehicles. It issues a severe thunderstorm watch when conditions are favourable for a storm to develop. A warning is issued when there is evidence that a thunderstorm is imminent or occurring that will produce damaging hail, wind or rain. Tornado watches and warnings follow a similar system.

Parts of Northern Ireland saw almost full month's worth of rain in 24 hours
Parts of Northern Ireland saw more than 85% of the average July rainfall come down over a 24-hour period, according to forecasters. Warnings over rain applied to significant parts of the island of Ireland on Monday following a night of heavy downpours. The deluge resulted in localised flooding across parts of the island following a series of weather alerts on Sunday, with the unseasonably high rainfall dampening the start of the week. The weather also brought difficult travelling conditions, lightning damage and poor visibility in the worst-affected areas. The Met Office issued a yellow-level rain warning for the east coast of Northern Ireland that is due to expire at 6pm. Forecasters had warned that some areas could see half a month's worth of rain in less than a day. The region normally records an average of 89mm of rain in July but falls of between 50-75mm had been predicted over a period of just 12 to 18 hours. Killowen in Co Down recorded 68mm of rain since 5pm on Sunday, the Met Office said around 2pm on Monday – the highest amount of rainfall across the UK. It normally sees 80.75mm of rain for the whole month. Elsewhere, Murlough in Co Down saw 60mm of rain in the same period – 87% of its July average of 69mm. The Met Office said other areas likely experienced higher amounts. Meanwhile, the heavy rain brought flooding at the Marble Arch Caves, a famous tourist attraction in Co Fermanagh. A spokesperson said it had never happened before, describing the occurrence as a 'highly unusual weather event'. A couple who were part of an evacuation prompted by a rush of water said they would not be put off returning. The agency had put a 24-hour yellow-level rain warning in place for Antrim, Armagh and Down until 6pm on Monday. A more intense amber-level warning was temporarily put in place overnight but lifted early. Forecasters had warned that there was a risk that homes and businesses could be flooded. The Met Office also cautioned that some communities could be cut off by flooded roads while fast-flowing or deep floodwater could pose a danger to life. A yellow-level thunderstorm warning was in place for the western half of Northern Ireland between midday and 8pm on Sunday. Flooding affected routes in Fermanagh with the Marble Arch Road, Florencecourt, and Sligo Road, Enniskillen, both described as impassable by police for a time. A PSNI spokeswoman said: 'Please take care when travelling, slow down, and exercise caution on affected roads.' In the Republic of Ireland, a status orange rain warning for Dublin, Louth, Meath and Wicklow came into effect from midnight and expired at 2pm on Monday. Irish national forecasting agency Met Eireann said there was a chance of thunderstorms amid persistent and heavy rain. A less severe warning for the Kildare region also expired at 2pm. The downpours across Sunday and Monday brought localised flooding to parts of Limerick and Louth. The warnings followed other alerts about thunderstorms in the east of the country and increased rain in the south-west on Sunday.

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. 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. 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.'
