This session covers a wide range of high impact weather-related topics and also includes the related aspects of risk, safety, and sounding. The session is split into two parts. One part will focus on recent developments of warning techniques and warning strategies including semi-automated warning systems and their use for the forecasters daily work. Another part will focus on best practice stories in extreme situations up to transnational scale and the way this kind of situations is dealt with within your organisation.

o flooding
o nuclear
o chemical or
o other extreme situations
on local up to transnational scale
