Hi Raymond,
the weather in Almeria a few days ago was extreme and freak, but you are right in wanting to be informed. At this moment, it is impossible to know what the weather will be like in your first days of Camino, but what happened just week is very unusual.
I imagine along the way you will be walking along "ramblas" (flat looking, dry river beds where water can run violently in case of extreme rains) also called "barrancos" (ravines) if they are narrower or more steep. Those are the natural drainways for excess water and you want to be careful if you need to walk around those areas.
This said, you would normally have time to reach a high, safe place in case of emergency.
The key is to be informed and talk to the locals. In the meantime, I would recommend you to download the AEMET official weather app, where you can see forecast by the hour or the day for your current location, radar/satellite pictures of cloud formations and general weather alerts (yellow, orange or red).
The Almeria amigos del camino seem to be very helpful and accesible, as far as I have seen.
As you go to higher altitudes, it can get chilly, beware of that too, the Sierra Nevada is right there.
BTW, I live in the province of Granada, not far from Almeria.
BUEN CAMINO!!!
