Spain, 19.08.2015. Description

Synoptic Situation

Summer morning situtation in the West of Spain, next to the Mediterranean sea. Light and unstable fluxes from the East at low levels. Slightly cold in upper levels. Very warm sea. Some of these situations can be serious, others not.

1. Will a strong storm develop in this situation? Can the NWC SAF Products help us in this?

2. Is the iSHAI product anticipating anything unusual?

3. Are there any convergences seen by HRW?

4. Is the RDT product detection convection cells? When?

5. How did other remote sensing systems detect the situation?

6. Is the CI product anticipating any storms?
