DANA: away from the water and up high, without hesitating.
A DANA can dump months of rain in a few hours. Flash floods arrive fast, even where it isn't raining. With an orange or red warning, the priority is to stay out of the water's path.

What people ask most
What is a DANA?
An isolated upper-level low (a "cold drop"): a pocket of cold air high up that, over a warm sea, can cause torrential rain in a very short time.
Why not cross a dry riverbed?
Because water can arrive all at once from areas where it is raining, even if not a drop is falling where you are.
What does each warning colour mean?
Yellow: take care. Orange: significant risk, get ready. Red: extraordinary risk, follow instructions and don't travel.
