Tomorrow (Sunday 13-March-2016) extremely bad weather is expected on south to north Iceland. The weather is also not going to be good in other parts of Iceland, but it is going to be far worse in south Iceland, western Iceland and north-western Iceland. With wind reaching 32m/s (115km/h) and with far stronger wind gusts. Today the weather has also not been good, but tomorrow it is going to be worse. Roads are going to get closed, as did happen today (12-March-2016). If you are in Iceland follow the closures since in this type of weather a rescue mission might not be possible due the the weather. The rescue crews might not even attempt reaching stuck people if it comes down to it. Since this strong wind is going to be followed by a warm weather and heavy snow melt at the same time, there is a risk of local floods in the next 24 hours.
This is only the weather forecast today. Tomorrow might get a lot worse if the weather forecast is off, that often happens in Iceland due to random factors of nature.
