WINDS travelling at speeds of up to 80mph could batter the south coast on Sunday and Monday according to forecasters.
The Met Office has also forecast showers on Sunday and heavy rain on Monday in the Portsmouth area.
A spokesman said ‘exposed coasts on the south’ are particularly vulnerable to the impact of a ‘significant’ storm predicted to develop close to the UK.
The storm is predicted to develop in the West Atlantic today and intensify west of the UK late on Sunday before tracking across England and Wales early on Monday.
The Met Office has issued an amber warning of wind on Monday.
It said ‘persistent, heavy rain’ could cause some surface water flooding’ in the south.
The office has warned people in the south to ‘be prepared for the risk of falling trees as well as damage to buildings and other structures.’
