They have put a level 1 into affect all the way from southern Sweden over eastern Germany, the Czech republic, Austria, western Slovakia/Hungary, Slovenia, parts of Croatia to northern Italy. In these regions, the main risks coming from thunderstorms will be large amounts of rain and possibly large hail. The amounts of rain may locally, especially in eastern Germany, be enhanced by the train effect, when several showers and/or thunderstorms move over the same location after each other, like the carts of a train.
