A number of weather warnings have been issued for Portsmouth and the surrounding areas for Saturday and Sunday.
It will be the second storm to batter the city in a week following Storm Ciara last weekend, which brought gale force winds and travel disruptions.
Here’s what residents can expect from Storm Dennis in the coming days:
What weather warnings have been issued?
The Met Office has put out a yellow alert for strong winds for across Hampshire including the Portsmouth area.
This is in place from 10am on Saturday until 11.59pm on Sunday – meaning it covers the vast majority of the weekend.
A yellow weather warning is also in place for heavy rain for Portsmouth and the surrounding towns.
It comes into force at noon on February 15 and will remain in place until 9pm on February 16.

What can residents expect?
With the yellow rain warning in place for much of the weekend, the Met Office has said that that Storm Dennis will bring ‘very heavy rain’.
There is a chance of flooding and disruption to travel over the weekend.
