Overview
- The Essex Region Conservation Authority had issued a flood watch for the region warning that record rainfall could cause watercourses to spill into low-lying areas as rain fell in concentrated bursts.
- Localized gauges recorded more than 30 millimetres in 12 hours with forecasters warning additional downpours could push some spots to very high short-term totals that overwhelmed drainage capacity.
- Windsor logged more than 800 storm-related calls after chaotic weather knocked out power to hundreds of homes and caused sections of the London, Little River and Grand Marais drains to overflow.
- City officials said sewer and storm systems were working as designed but were overwhelmed by the volume of water, and they urged residents to contact insurers before cleanup and to file Windsor 311 requests for basement flooding or tree damage.
- To support recovery the city and Miller Waste will run a special two-week tree-waste collection with set size and weight limits and will pick up flood-damaged materials after residents register for curbside service, highlighting ongoing strain on local infrastructure and public health risks from standing or sewage-contaminated water.
