Excessive Heat

Local residents tend to dismiss the notion that we could have heat related problems. Globally, however, there is a growing recognition that heat can be a significant hazard. From as far away as France to as close as Chicago right here in America we have seen heat waves that have killed hundreds of people.. Yet heat is a silent hazard, affecting vulnerable populations individually in their homes. Due to the severity of the problem it is worth evaluating where Seattle is in terms of risk.

While good meteorological records exist, heat waves are more complex that just high temperatures. Other factors like the rapidity of the temperature rise, the humidity, the duration, and the availability of cooling systems all strongly influence the effect. Because of these factors and the recognition of heat as a source of disaster only recently, records are marginal. The "Major Incidents" chart below probably under represents actual incidents.

Issues to Note

Although Seattle is not as likely to suffer extreme heat as many other cities, we are vulnerable to heat when it occurs because many residents lack efficient cooling systems in their homes or businesses and remain unaware about how to protect themselves. The difference between the normal temperature for the period and the current temperature dictates the real impact that heat has on the individual. Since we normally have fairly mild temperatures, our population can feel stressed at lower temperatures than many other places, especially if the rise happens suddenly.
