Detecting an extreme temperature event. A method includes collecting raw data from a high resolution sensor. The method further includes identifying in the raw collected data one or more changing data point values. The method further includes identifying, in the raw collected data that the one or more changing data point values have reached a determined threshold that indicates with a high level of probability that an extreme temperature event has occurred. Alternatively, the method may include identifying in the raw collected data a sudden extreme increase in one or more data point values that cross a threshold which indicates with a high level of probability that an extreme temperature event has occurred. As a result, the method includes issuing an alert indicating that an extreme temperature event has occurred.
