Note: The prediction is for the upcoming 12 - 24 hours and does not necessarily
reflect the current weather situation. It calculates based on the pressure changes that
have occurred during the past 24 hours the most likely weather forecast for the
upcoming 12 - 24 hours. The weather forecast predicted has a probability of 70%. This
means that observed over a period of several weeks, 7 from 10 forecasts for the
