As temperatures rise, more moisture is evaporating into the air, leading to <strong>heavier rainfalls<\/strong> and<strong> bigger storms. <\/strong>Some of these storms are powerful tropical storms like cyclones, hurricanes, and typhoons.<\/p>\n\n<p>As storms get worse, communities are experiencing more severe and unpredictable flooding. It\u2019s a concern for Canadians! Over <a href=\"https:\/\/climateinstitute.ca\/flood-insurance-risks-canada\/\">1.5 million homes<\/a> across Canada are in areas at high risk of flooding. <a href=\"https:\/\/www.publicsafety.gc.ca\/cnt\/rsrcs\/pblctns\/vltn-ntnl-dsstr-mtgtn-prgrm-2019\/index-en.aspx\">Eighty per cent<\/a> of Canadian cities are on floodplains.<\/p>\n\n<h2 class=\"wp-block-heading\">What is a flash flood?<\/h2>\n\n<p><strong>Flash floods<\/strong> can be dangerous because they happen fast, giving people little time to prepare. They usually take place in the first six hours after a very heavy rainfall. The ground can\u2019t soak up the water quickly enough. Instead, flood waters run over the ground\u2019s surface.<\/p>\n\n<p>Materials like concrete cover a lot of the soil in cities. This makes it even harder for the ground to absorb rain water. On July 16, 2024, nearly 10 centimetres of rain fell in three hours in Toronto, knocking out power for <a href=\"https:\/\/www.cbc.ca\/news\/canada\/toronto\/rain-thunderstorm-warning-gta-1.7264873\">over 100,000 people<\/a> and flooding the streets and subways.<\/p>\n\n<h2 class=\"wp-block-heading\"><strong>The extreme cost of extreme weather<\/strong><\/h2>\n\n<p>As the number of heatwaves, wildfires, storms, and floods rises, so will the cost to Canadians. Extreme weather in Canada caused over $3.1 billion in insured damages to homes and other property in <a href=\"https:\/\/www.ibc.ca\/news-insights\/news\/severe-weather-in-2022-caused-3-1-billion-in-insured-damage-making-it-the-3rd-worst-year-for-insured-damage-in-canadian-history\">2022<\/a> and <a href=\"https:\/\/www.ibc.ca\/news-insights\/news\/severe-weather-in-2023-caused-over-3-1-billion-in-insured-damage\">2023<\/a>.

It affects our health. It can lower our quality of life and cause illness and death. And it doesn\u2019t harm the health of all people equally.&nbsp;<\/p>\n\n<p>Communities that are already treated unequally face <a href=\"https:\/\/www.canada.ca\/en\/health-canada\/services\/climate-change-health\/populations-risk.html\">bigger health challenges<\/a>, like Black, Indigenous, people of colour, women, and LGBTQIA2S+ communities.
