This year we started naming storms - and let's face it, some are rather amusing (storm Nigel, anyone?). But why does this system exist and how does it work? Laura is here to explain.
It's been a stormy week for many - and more wet and windy weather is due over the weekend. Laura Tobin tells us more in her Friday outlook for the next couple of days.
Large parts of the UK have seen some very rare clouds that looks like a sheet of rainbow across the skies over the last few days. Lots of people thought they were rainbows in the sky or the northern lights.
They are actually a rare cloud called nacreous clouds or polar stratospheric clouds, they are also known as mother of pearl due to their iridescent appearance.
They occur in the winter polar stratosphere (the atmosphere above the one our weather occurs) over 50,000 ft high,15–25KM. They are usually spotted just before dawn or just after dusk, when the sun is between 1 and 6 degrees below the horizon, meaning these clouds receive sunlight from below the horizon and reflect it to the ground.
The stratosphere is very dry-unlike the troposphere (where out weather happens) and it rarely allows clouds to form, so keep your eyes peeled and you may spot more of them over the coming days.
Britain is bracing itself for more bad weather as Storm Henry is expected to hit later today with winds gusting up to 90 miles an hour.
Laura has the full update as well as a look ahead to what's in storm for this week.
- The Met Office has issued an amber warning as gusts of 90mph and heavy rain head for the UK's Friday morning rush hour.
- A yellow warning for snow and ice has also been issued for the majority of Scotland and parts of northern England, which are likely to hit later in the day.
- Take care: gusts between 60mph and 80mph, especially near coastal areas, and heavy rain threaten to lash these areas between 3am and 10am on Friday and drenching areas with heavy rain.
- Strong winds are also headed for Northern Ireland as well as in England, Scotland and in the Northern Isles (could be up to 90mph!).
- Take care: Big waves, damage to power cables and structures is expected along with ferry and rail cancellations.
- Plan ahead: Lots of bridges and roads have already been closed.
- Gertrude has been named so the public are more aware of these storms over a 'normal' winter storm, and able to keep themselves, their property and businesses safe.
I might be speaking for myself, but I was a little excited pulling out my windscreen scraper for the first time this winter last Saturday morning as I prepared to stand on the sideline at football cheering on my son in the bitter cold.
It was a sure taste of things to come as this week saw cold air blasted across Britain, holding temperatures in the low single figures during the day, only to be forced to the other side of the Mercury at night, ensuring some frosty mornings.
Kinbrace, Upper Lambourn and Benson were all in the top five coldest places this week with temperatures colder than minus 8.
