Tomorrow, it's seven years since nightmare became reality for the US

state Lousiana with the arrival of Hurricane Katrina. The swirl of

cloud is turning into Hurricane Isaac. Hurricane Isaac is not

Katrina. It's a dangerous storm when it comes to the flooding

potential from that storm surge and all the heavy rain that is about to

fall from that side of the Atlantic we will hear more from Hurricane

Isaac. This swirl of cloud will make an impact on us. It is into

Ireland. It pushes across Northern Ireland, Scotland, Wales & West

earn England as the night goes on. Your sleep may be disturbed.

Eastern England will stay dry. Tomorrow, the rain will move

eastwards, following on behind heavy showers. Here is how it looks

in the morning. A wet day into Shetland. For Northern Ireland and

Scotland the over night rain has gone, but the showers aren't too

far away. Out of Wales and into the Midlands the rain will move. The

rain will head in for the afternoon. The rain will move east into the

afternoon. Behind it brighter weather will follow. Northern

Ireland, South West Scotland and northern England could have

torrential downpours with local flooding. Temperatures not up to

much. The rain should clear for the Opening Ceremony of the Paralympics.

I can't rule out a passing shower for the big event. On Thursday

England and Wales will have the showers. Scotland and Northern

Ireland dry and bright. A chilly night will follow on Thursday night.
