As expected we saw a big change in the weather over the weekend.
Saturday was lovely with plenty of sunshine but on Sunday it started to go downhill with heavy rain spreading from the south reaching the north by the evening.
It was also cool yesterday. In fact at Velindre near Glasbury in Powys, the temperature failed to reach 10 Celsius, making it the coldest September day there since 1974!
In Llanarmon Dyffryn Ceiriog near Wrexham nearly a month's worth of rain, over 80mm (3 inches), has fallen in the last 24 hours.
This has led to some disruption with a few roads closed due to flooding and rail services affected as well.
At the time of writing, there are 13 flood alerts in force.
Most of the really heavy rain has cleared from most of the country but more rain is forecast in the next 24 hours, especially in the north and west. Strong winds in places too.
There is a Met Office Amber warning in force for the north until 6am Tuesday plus a general yellow warning covering the whole country with further disruption possible.
Amber means be prepared!
Tomorrow night further showers or longer spells of rain are expected, heavy in places.
Wednesday will bring an improvement - breezy or windy with scattered showers; heavy in places but some dry and bright spells too.
Thursday will be much drier, the wind easing as well.
Friday will start dry followed by a little rain.
