Temperatures could hit 30 degrees in some parts of the country today.

We're in for another spell of very warm weather, with a status yellow high temperature alert now in place for Tipperary and all of Leinster, lasting until Friday morning.

Met Éireann is warning of heat stress, animal welfare issues, uncomfortable sleeping conditions and water safety concerns as people head to rivers, lakes and beaches.

Cathal Nolan from Ireland's Weather Channel says it could be even warmer than expected. "One or two pockets of Leinster could see temperatures up to 30 degrees, he said.

"It's parts of Leinster that are likely to see the highest temperatures today, for examples areas in and around the greater Dublin area, parts of Kildare, into parts of Carlow, Laois, and Offaly. These areas could see temperatures up close to 30 degrees."
