• Parts of Milford Haven and the surrounding area experienced a 'mini-twister' last night.
The twister - or funnel cloud - was spotted by Michael Harris of Milford Haven who captured the photograph on this page.
He said: "The funnel cloud was coming down over Hakin on 5th July at 6.30pm. Unfortunately it didn't touch down to make a tornado, but could clearly be seen spinning."
Tasha Rees of Steynton added: "I saw it out of my bedroom window. It didnt really make any noise, but it was windy. I saw the mini tornado forming.
"The sky was white, appart from this cloud, it was dark. I could see that it was spinning, and could see it getting bigger, the bottom of it getting larger and almost touching the ground.
"Around 10 mins later it was gone and the sky was white again." Tasha Rees
National Park Discovery Ranger Tom Moses added: "I was leaving our Llanion HQ and looked towards Waterston- the funnel cloud was pretty obvious as it reached down from the dark thunder cloud. "As a National Park Discovery Ranger I was immediately really excited and grabbed my camera - this is a brilliant example of the amazing things you can see if you keep your eyes peeled when out and about. "I’m a bit gutted we didn’t get a waterspout in the Haven."
