This is the most widely warned weather in Canada today, and it is rain rather than wind or fire.

The Environment and Climate Change Canada alert feed, read at 5:00 this morning Universal time, carries 283 active alerts nationally. Of those, 191 are rainfall warnings in Saskatchewan, 72 are rainfall warnings in Alberta, and eight are rainfall warnings in Manitoba. One further rainfall warning spans the Saskatchewan and Alberta boundary. Together the three provinces hold 272 of the country's 283 alerts.

The Alberta warning, issued at 4:21 yesterday afternoon Mountain time, states that heavy rainfall will continue with total amounts of 40 to 70 millimetres expected and localized totals up to 100 millimetres possible, ending today. The Saskatchewan and Manitoba warnings, issued at 3:55 and 4:55 yesterday afternoon Central time, state that rain continues in much of Saskatchewan and parts of Manitoba with a further 10 to 50 millimetres expected overnight, and that rain will continue in many areas today without further significant amounts.

A rainfall warning in Canada is issued when enough rain is expected to cause flooding or water pooling. It is a yellow level warning, the same tier as a wind warning. It is not the highest product Environment Canada issues, and it is not an evacuation product.

One hundred millimetres is about four inches. On the Prairies, where the ground is flat and drainage is slow, that produces water standing on roads and in low areas rather than fast moving flood. The warning text names the two specific hazards: water pooling on roads and in low lying areas, and visibility suddenly reduced at times.

The Environment Canada guidance in the warning is direct and it is the right guidance. Do not drive through flooded roadways. Allow extra time for travel. Avoid low lying areas. Water across a road hides what the road is doing underneath it, and a vehicle needs less water than most people expect before it starts to float.

Warned areas in Saskatchewan include the cities of Saskatoon and Prince Albert and rural municipalities across most of the province. In Alberta they run from Beaver County in the centre through Cardston County in the south. In Manitoba they include the Duck Mountain provincial park and forest area.

The fire picture across the three provinces is quiet, which is a genuine change from earlier in the season.

The Canadian Interagency Forest Fire Centre's national situation report for September 7 shows Alberta with one fire under full response and Saskatchewan with none. Manitoba has one being held. All three provinces report an agency preparedness level of 1, the lowest on the scale.

Season totals stand at 742 fires and 17,739 hectares in Alberta, 336 fires and 303,309 hectares in Saskatchewan, and 313 fires and 264,244 hectares in Manitoba. One new fire started in Manitoba yesterday and none in Alberta or Saskatchewan.

The Canadian Interagency Forest Fire Centre's national situation report for September 7 puts the national preparedness level at 3 on a five step scale, with 97 fires under full response across the country, of which 21 are out of control, 19 are being held, and 57 are under control. The season total stands at 5,303 fires and 4,484,135 hectares.

For roads, prolonged rain on flat ground is a grade and culvert problem rather than a bridge problem. The failures that happen are gravel roads softening and culverts backing up, both of which show up as a road that looks passable and is not.

Rural households on gravel access roads have a specific version of this: if your driveway or your road crosses a culvert, that is the point that fails first, and it is worth knowing whether you have a second way out.

No air quality alerts are active in Alberta, Saskatchewan, or Manitoba. The one air quality warning in the country is in the Northwest Territories, at Fort Simpson.

The health item that goes with prolonged rain is water in basements, and the risk there is electrical rather than biological. Standing water in a basement with live circuits is not a place to walk. The order is power off at the panel first, then assess.

If water does get in, the cleanup is a ventilation and disinfection job rather than a mop and go job, because material that stays damp grows mould within a couple of days.

No boil water advisories were identified across the three provinces.

The rain ends today, and after it the pattern turns toward autumn.

Both the Alberta and the Saskatchewan warnings state that the rain ends today, with Saskatchewan and Manitoba seeing continued showers without further significant totals. This is a one event situation rather than a multi day one.

The forward looking item is what follows. Early September on the Prairies is the start of the window where the first hard frost arrives, and it is roughly two months from the first blizzard conditions. The autumn checklist here is the one that gets done in September or gets done badly in November: tires checked before the first snow, a blanket and a shovel back in the vehicle, and the furnace serviced while a service call still gets answered the same week.

That last one carries the season's quiet hazard. Every autumn the first cold night brings the furnace on for the first time in months, and carbon monoxide alarms with dead batteries are why that matters. Carbon monoxide has no smell and no colour. The alarm is the only thing that detects it, and an alarm more than ten years old is past its rated sensor life and needs replacing rather than a new battery.

For anyone who heats with a wood stove or uses a generator during outages, the same rule applies with more force: those appliances belong outdoors or properly vented, never in a garage or a porch, and never with the exhaust anywhere near a window or a vent.

The wet ground now is also worth remembering in a month. Saturated soil freezes differently than dry soil, and the first freeze after a wet autumn heaves driveways, walkways, and shallow water lines more than usual.
