Windspeed conversions
The Icelandic Meteorological Office uses the SI (Systeme Internationale d´Unites) unit metres per second (m/s) in windspeed measurements. Here you can convert between different units of windspeed. Type a number into a textbox below and then click outside it. Please note that Beaufort-values are between 0 and 12.

a systematic com-
parison of results to observed precipitation has been carried out. Un-
dercatchment of solid precipitation is dealt with by looking only at
days when precipitation is presumably liquid or by considering the
occurrence and non-occurrence of precipitation. Away from non-
resolved orography, the long term means (months, years) of observed
and simulated precipitation are often

and snow on higher ground, especially in the North. It is not possible yet to predict the actual path of the low-pressure and hence it is not possible to say which area of the country will be most affected.
Readers are encouraged to check the updated text forecast regularly. For the time being the forecast for the next few days is such:
On Thursday: Southerly wind 5 to 10 m/s and some rain

-DEM (5x5 m
spatial resolution with accuracy <2 m in elevation) was used as a reference map for co-
registering and offset-correction of the HRS-DEMs (40x40 m) and the DMA-DEMs (40x40 m
interpolated from 20 m contour lines). The average specific mass balance was estimated as
the mean elevation difference between glaciated areas of the DEMs. The glacier mass
balance declined significantly between

gale or severe gale warning (average wind velocity 20 to 28 m/s) is in effect for all parts of Iceland today, and in Westfjords and tonight and tomorrow.
Weather forecast for the next 26 hours:
Today (Wednesday): East winds, 20 to 28 m/s with snow in the south and west part of Iceland, but later sleet and rain by the coast. East 18 to 28 m/s in the afternoon, strongest winds by the coast

Wind speeds measuring 20 m/s and higher were recorded at half of the automatic weather stations in the lowland areas and similar speeds were recorded at 80% of automatic weather stations in the highland areas.
In the town of Heimaey in the Westman Islands, wind-speed* of 28 m/s and gusts measuring 45.8 m/s were recorded at the height of the storm, setting

where c is the speed of light (c = 2.99 x 108 m/s). In principle, CL51 is able to detect three cloud
layers simultaneously, but if the cloud base is obscured due to precipitation or ground-based
fog, vertical visibility is reported. Information about fog and precipitation can also be derived
from the return signal as they attenuate the return signal from a cloud. In its
