The volcanic eruption in Holuhraun was well visible on web-cameras tonight and into the morning. The eruption
appeared to continue with similar intensity. Visibility in the area is now very bad and nothing to see on web

isobars signify the air pressure, in millibars, at the ocean surface (1 mb = 1 hPa).
The red, purple and blue isotherms show the temperature at 2 m above the ocean surface. A blue line denotes sub-freezing conditions; a purple line denotes 0°C and; a red line denotes temperatures above freezing.
Wind speed is displayed in metres per second (m/s).
The angle of the wind barb is indicative

Weather observations are made to acquire information about the state of the atmosphere. The following factors are the most important observations, and they are relatively easy to measure:
Temperature
Air pressure
Wind at the Earth’s surface
These factors are either measured with automatic meters or a weather observer reads the meters or evaluates the observation in some way

Air quality in urban areas in the East of Iceland:
o Forecasts indicate that high concentrations of sulphuric gases may be
expected in the northern part of the Eastern fjords, Fljótsdalur, Hérað,
Jökuldalur, and Vopnafjörður. High concentrations could occur in other areas
as well. People who feel discomfort are advised to stay indoors, close the
windows
