Is it weather forecast information?

Weather forecast belongs to information.

Information refers to all the contents spread by human society. People can distinguish different things by obtaining and identifying different information from nature and society, so as to understand and transform the world.

Physically speaking, information and matter are two different concepts. Information is not matter. Although the transmission of information requires energy, information itself has no energy. The most striking feature of information is that it cannot exist independently, and the existence of information must depend on the carrier.

Extended data:

Although the information is uncertain, there are ways to quantify it. The greater the probability P(x) of message appearance, the smaller the amount of information; Conversely, the smaller the probability of occurrence, the greater the amount of information.

As you can see, the amount of information (which we refer to as I) is inversely proportional to the probability of message occurrence. When the probability is 1, everyone in the world knows what happened, so the amount of information is 0.
