it is when the weather is very bad or for example hazordous.
The three types of hazardous weather forecasts are watches, warnings, and advisories. A watch means conditions are favorable for hazardous weather, a warning means hazardous weather is imminent or already occurring, and an advisory means hazardous conditions are expected but less severe than a warning.
Hazardous weather
Three types of hazardous weather forecasts are weather advisories, weather watches, and weather warnings.
Hazardous wastes are materials that are to be discarded (i.e. are wastes) but can be a danger to people or to the environment and meet the definition based on the identity of the material or on test results. If hazardous wastes are mixed with the nonhazardous wastes, the result is a hazardous waste. A non-hazardous waste is something that is to be discarded (i.e is a waste) but does not meet the definition of a hazardous waste.
