A yellow warning for high temperatures, which are expected to reach up to 42C, has been issued for Wednesday while a red alert for forest fires remains in place.

The weather alert will be in force from 12 to 6pm, according to the met service.

It said the maximum temperature will be recorded inland at an estimated 42C, while in the higher mountains temperature will average at 33C.

Regarding the red alert for fires, the forestry department issued a strong appeal to the public to be particularly careful during their outings, avoiding actions and activities that are likely to cause a fire, such as the use of tools or agricultural machinery that produce heat, sparks or flames.
