Why do you never report the weather forecast when the temperature exceeds 40 degrees?

In fact, many people don't care about this statement, that is, when the temperature reaches 40 degrees or above, no matter what kind of outdoor work units have to have a holiday, which may be detrimental to the development of these enterprises. Therefore, the Meteorological Observatory concealed this true situation, which is actually an irresponsible guess. First of all, the meteorological station must be broadcasting today's weather with a certain professional quality, although the weather broadcast by the meteorological station is not 100. Accurate, because the weather may change at any time while the weather station forecasts, so the weather we see is often updated from time to time, and relevant regulations indicate that when the temperature reaches above 35 degrees, the outdoor operation time must be shortened as much as possible, and when it reaches above 40 degrees, the outdoor operation must be stopped in time to avoid heatstroke and even casualties.
