On IMO's avalanche forecast maps, an international colour code is used, see below. The table and the icons are from EAWS.
A specific map is presented for each of three selected high risk areas. Additionally, IMO issues

Keep in mind that short-term forecasts are more likely to be correct than long-term forecasts.
The sliding bar beneath the map is used to view the various forecast periods. It is possible to click on the sliding bar, the days, the hours, or the arrows at the either end of the bar. Additionally, the left

Additionally, see a panoramic photo (20.1.2015) provided by Njáll Fannar Reynisson, IMO, as well as two series from 21 January; a photo gallery from the bridge and aerial photos from a surveillance flight.

Rainfall-induced flooding is occurring on Barðaströnd, Snæfellsness, and at the Mýrdalsjökull ice-cap. Additionally/about-imo/news/on-the-weather-forecast-and-the-flood-conditions
are international and countries exchange large amounts of data on a daily basis. Additionally, synchronous observations are made worldwide, allowing the state of the atmosphere to be mapped and examined.
Frequent observations made over long periods allow global atmospheric changes such as the enhanced greenhouse effect to be monitored and detected.
Weather observations are also necessary

predictions can be made.
The solar wind consists mainly of protons and electrons travelling from the Sun at great speeds. It takes these particles about 1-3 days to reach Earth and therefore it is possible to predict major geomagnetic storms. Additionally, particle flux hits the ACE-satellite about one hour before it hits Earth and therefore it is possible to make quite reliable aurora

is being returned back to green although the long-term trend of activity at Grímsvötn is considered to be above normal background levels. The month-scale seismic activity at Grímsvötn volcano shows an unusual trend characterized by a larger number and more intense earthquakes than before. This trend has been slowly increasing over the past months. Additionally, the deformation has already exceeded
