More about the Forecasts
- The forecasts provided are obtained automatically through statistical processing of numerical models and are updated twice a day (the first between 07 and 09 UTC, and the second twelve hours later).
- The forecasts are presented in UTC time. On the mainland and in the Autonomous Region of Madeira, local time coincides with UTC during winter time and becomes UTC+1 in summer time. Thus, in these regions, 10 UTC corresponds to 10 local time in winter and 11 in summer. In the Autonomous Region of the Azores, local time is UTC 1 in winter and UTC in summer.
- In some meteorological situations, numerical models struggle to accurately capture the actual weather conditions. They often show notable limitations in pinpointing the precise timing and location of cloud cover and precipitation, with spatial errors commonly ranging from 30 to 50 km and timing discrepancies of roughly 1 to 3 hours.
- These forecasts may be different from the ones issued by forecasters because they have additional and updated information, so the user is advised to check these forecasts and any warnings.
- To assess the level of confidence in the forecast, two values of probability of precipitation are presented:
- in the daily forecast, the probability of precipitation (greater than or equal to 1 mm/24 h) is presented. This probability ranges from 0 to 100% and is intended to provide a degree of confidence in the forecast for that day.
- in the hourly/three hourly forecast, the probability of precipitation (greater than or equal to 0.3 mm) in the last three hours is presented. This value is useful to assess the time of the day when precipitation is more likely to occur. However, in certain meteorological situations, precipitation may or may not occur regardless of the probability values.
- The Apparent temperature is an estimate of how our body senses the actual air temperature, taking into account environmental factors that modify this sensation, and is calculated from the air temperature, relative humidity at 2 m, and wind speed.
