Derecho 29.7.2013

Postautor: Tomáš_Prouza » niedziela, 4 sie 2013, 07:41

During 29th and early morning 30th July 2013 violent storm system passed over central Europe, affecting Austria, Czech republic and Poland. In all mentioned countries were observed strong wind gusts, heavy rain or hailstorms. Especially wind gusts caused a lot of damage on buildings and vegetation.

It seems event met parameters to be marked as derecho:

Actual version of the derecho map will be available at this link.

Numbers are measured wind gusts, red ones higher than 33 m/s. Blue dots represent reported damages caused by wind (regionally, there were hundreds of single events). Black dots represent wind damages equivalent to tornado F1 or stronger (but not caused by tornado!). Violet lines represent forehead of system in space-time (including time-stamps).

We would like to add more info into it in next hours and days. We have to find more damage reports even here in Czech Republic (57 reports in ESWD so far). If you have info about damage caused in Poland by wind which is not in the map, please write down here and we will add it into the map (and EWSD if not recorded yet).

Thanks in advance for your cooperation.

P.S. Same day was chosen (due to expected conditions) for experimental RSS 2,5 minute imaging. Following video was compiled using images taken by Meteosat 8 during experimental 2.5min rapid scanning service between 9:00 and 21:00 UTC on 29. July 2013.
