St Mary's Harbour has described the sea state over the weekend as "concerning". 

In an update on social media, they said that storm boards at Porthloo were to be put out this afternoon and will hopefully be removed on Saturday lunchtime when the worst of the weather has passed. 

They added: "We advise all boat owners not to go afloat unless it is absolutely necessary. We expect some over-topping on the quay at each high water (HW) and advise everyone to refrain from viewing the storm close to the water's edge or on the quay. Stay on high ground to avoid being caught out!" 


HW Times are as follows:

Friday - 18:23
Saturday - 06:44 & 19:05
Sunday - 07:25 & 19:47
Monday - 08:08 & 20:30


The Harbour staff concluded the post with: "STAY SAFE!"


The Scillonian has been cancelled tomorrow due to predictions of gale force winds but will sail twice on Sunday. 


Meanwhile, the Council of the Isles of Scilly have posted extreme flooding information on their website which reads:


Extreme Flooding is expected for Isles of Scilly including St Mary's, St Agnes, Bryher, Tresco and St Martins for 2 hours either side of all high tides between 19 Aug 2016 18:24hrs until 20 Aug 2016 19:05hrs


Forecast tide levels and sea conditions for the Isles of Scilly, from 19 Aug 2016 18:24hrs until 20 Aug 2016 19:05hrs high tide is likely to cause LARGE impacts including risk to life, damage and flooding to property and critical infrastructure.


In liaison with the Council of the Isles of Scilly, EXTREME Flooding Information has been issued.


The Environment Agency recommends that extreme caution is exercised at least 2 hours either side of high tide due to the extreme wave climate and high water levels. In addition to wave and sea over-topping, there may be a risk of flying debris.
