uncertain
buildings → blow → storm
A number of schools are closed in the impacted areas with many others opening later than usual to avoid the strongest winds.
asserted
others → close → winds

Is it unusual to see two storms so close together?
It is not unusual to get storms one after another - in fact they quite often arrive in clusters.
A strong jet stream is needed to rapidly develop powerful wind storms.
asserted
stream → follow → storms
The process involved in creating such storms involves shifting warmer air northwards and cooler air southwards across vast areas of the Atlantic.
asserted
process → involve → Atlantic
These temperature contrasts can provide a fertile environment for new low pressure systems to develop and if these subsequently get steered beneath a developmental area of a powerful jet stream, they can rapidly develop to create a new named storm with damaging winds.
asserted
they → provide → winds
When do we see the most named storms?
asserted
we → see → storms
Although named storms can affect the UK at any time of the year, analysis shows they are much less common in spring and early summer.

uncertain

The chances of seeing a storm increases from late summer and throughout autumn with the peak of the season arriving in our winter months.

This increase in storminess is why the storm-naming season begins in September each year.
