What does ESTOFEX forecast?
ESTOFEX issues "Storm Forecasts" on a daily basis. These bulletins, accompanied by a map, address the threats posed by severe convective storms in Europe. The focus of the forecasts is the threat for hail, severe wind gusts, and tornadoes that these storms pose. Since May 1st 2009, the threat of excessive convective rainfall is included. Additionally, areas where lightning is expected are highlighted.
To communicate the magnitude of the threat of hail, severe wind gusts, tornadoes, and excessive precipitation, ESTOFEX uses threat levels. Threat levels are issued based on the estimated probability of severe weather resulting from convective storms. A storm is considered severe or extremely severe when it is accompanied by one or several phenomena that meet the criteria listed below.
severe convective weather phenomena:
hail with a diameter of at least 2.0 cm
tornado
wind gusts with a speed of at least 25 m/s (92 km/h or about 48.6 knots)
excessive rainfall of at least 60 mm (explained elsewhere in this FAQ)
extremely severe convective weather phenomena:
hail with a diameter of at least 5.0 cm
wind gusts with a speed of at least 33 m/s (about 119 km/h or 65 knots), or
a tornado of class F2 or stronger
