Each entry names the authority it comes from, the date it was checked and what it cannot establish. For an active emergency, follow official authorities and local instructions. This is not an emergency notification service.
Climate context for your region
Long-run temperature and precipitation shape what equipment has to cope with across a year, and how hard it works in the extremes at either end.
Building systems that may deserve review
- Heating
- Cooling
- Ventilation
- Envelope improvements
- Controls and automation
Documentation worth retaining beforehand
- Equipment capacity as documented on the rating plate
- Design conditions used at installation, if a design record exists
- Insulation and glazing records
- Control setpoints and schedules as commissioned
Evidence worth collecting afterwards
- Nothing. This is background, not an event.

Limitations. Station-based, so a locality without a nearby station is represented by one that may be some distance away. Not a forecast, and not a basis for equipment sizing.
External resource. Checked 2026-09-03.
This is regional context from the identified authority. It does not establish whether a particular building was affected or determine the building’s condition.
Extreme heat
Sustained heat puts cooling equipment near its limits for long periods and makes envelope and shading evidence relevant. Whether a particular building stays comfortable depends on the building, which regional data cannot tell you.
Building systems that may deserve review
- Cooling
- Ventilation
- Envelope improvements
- Controls and automation
- Backup power
- Critical-load panels
Documentation worth retaining beforehand
- Cooling equipment identity and capacity
- Last service record
- Glazing, shading and insulation records
- Which loads are on backup power, if any
Evidence worth collecting afterwards
- Note any period the equipment could not hold setpoint
- Photograph anything that failed, before it is repaired
- Keep the service invoice with the equipment record

Extreme cold
Deep cold is when backup heat, fuel supply and power continuity matter, and when a heat pump’s documented low-temperature behaviour becomes the question rather than a detail.
Building systems that may deserve review
- Heating
- Air-source heat pump
- Cold-climate air-source heat pump
- Hybrid or dual-fuel system
- Envelope improvements
- Standby or portable generator connection
- Critical-load panels
Documentation worth retaining beforehand
- Heating equipment identity and documented capacity
- Backup or supplementary heat arrangement
- Changeover control settings for a dual-fuel system
- Generator or transfer equipment records and last tested date
Evidence worth collecting afterwards
- Record any loss of heat and how long it lasted
- Keep the service record with the equipment
- Note anything that froze, and where

Wildfire, regional and historical
Historical wildfire occurrence in a region is context for documentation decisions about ventilation, filtration and exterior equipment. It is not a statement about the current fire situation.
Building systems that may deserve review
- Ventilation
- Heat and energy recovery ventilation
- Cooling
- Roof
- Solar photovoltaic
Documentation worth retaining beforehand
- Ventilation and filtration equipment identity
- Filter specification as installed
- Roof and exterior equipment records
Evidence worth collecting afterwards
- Photograph exterior equipment and roof surfaces before anything is cleaned
- Keep any post-event service or cleaning invoice with the equipment record
