Flying debris could lead to Injuries or danger to life

This is alongside a yellow weather warning for rain which covers most of Wales except Pembrokeshire and Anglesey.
Met Office chief forecaster Neil Armstrong said: "An extremely strong jet stream flowing from North America will be steering a succession of low-pressure systems towards the UK at least into the middle of next week.
"The relative predictability of this pattern has provided an early warning and has given us the certainty to be able to name this storm four days ahead.”
The amber warning for wind covers also covers all of England south of the Humber.
The weather warning is in place at the same time that many people will be travelling back from Dublin after watching Wales in the Six Nations.
Cardiff Airport has advised people to check with their airlines before travelling.
Forecaster MetCheck says: "Gusts of 100mph+ are possible across peaks of Wicklow mountains and Western Cambrian Mountains late Sunday morning and early Sunday afternoon.
"Heavy rain will also develop on the cold front which moves Southeast through the course of the day with a moderate risk of a squall developing."
