What does 100 percent rain forecast means?

The forecast didn't say "100 percent rain". It said "100 percent chance of rain".That means that the conditions that cause rain are so perfect that you can besure of it, and there's no question: It's definitely going to rain.

Does a forty five percent of chance rain mean that it will rain?

No. It means there's a forty five per cent change of rain. ========================================== When a weather forecast says that there is 'a forty five percent of chance rain,' that means neither that it will rain nor that it will not rain. It certainly indicates that rain is possible, however, and that the chances are almost 50/50 either way. Weather forecasting is not and never will be an exact science. Weather is highly variable at the best of times. All that a meteorologist can do is analyze data, apply it to various models, and make an educated guess. Nevertheless, weather forecasting is much more accurate today than it has ever been before. A 45% chance of rain is really saying that there is a reasonably good chance that you might experience rain. Based on that information, you can decide if you should take an umbrella with you.


The weather forecast says there is a 60 percent chance of rain today and a 40 percent chance of rain tomorrow What is the probability that it will rain today and tomorrow?

The probability that it will rain today and tomorrow is the multiplication of the probabilities of it raining both days. That is 0.6 X 0.4 = 0.24 So there is a 24% chance that it would rain both days.

Does a forty five percent chance of rain mean that it will rain?

Good question. The public perceives the statement with several meanings -- 45% of the weather forecast area will see rain tomorrow; the probability of rain in any region covered in the forecast is 45% tomorrow; "it might rain tomorrow"; 45 out of 100 (almost 50:50) cases that tomorrow we shall see some participation, based on today's weather conditions and what happened in the past; etc. Which is correct?I suggest reading the related links. Also read the books by Professors Edward Burger and Michael Starbird.==============================No. It means there's a forty five per cent change of rain. ========================================== When a weather forecast says that there is 'a forty five percent of chance rain,' that means neither that it will rain nor that it will not rain.
