The Met Office has issued a London-wide yellow weather warning of snow and ice across the capital including Harrow.
The news comes as Harrow Council have activated Severe Weather Protocol due to plummeting temperatures in the borough.
Met Office Chief Meteorologist, Steve Willington, said: “It is staying cold with daytime temperatures remaining only a few degrees above freezing in many places over the coming days and overnight temperatures dropping to -10°C or lower in isolated spots. Although below average, these temperatures are not that unusual for this time of year.
“There is still a risk we could see some freezing fog in places particularly southern England, especially for Sunday and Monday mornings. And there is also a small risk of a band of sleet or snow moving into the far Southeast on Sunday. If this happens it could potentially bring some disruption, especially to rush hour on Monday. A warning has been issued.”
The Met Office issued the warning today (Friday, December 9) and will come into effect in Harrow on Sunday going into Monday.
Dr Agostinho Sousa, Consultant in Public Health Medicine at UKHSA, said: “Cold weather can have serious consequences for health, and older people and those with heart or lung conditions can be particularly at risk.
“If you have a pre-existing medical condition, you should heat your home to a temperature that is comfortable for you. In rooms you mostly use such as the living room or bedroom, try to heat them to at least 18°C if you can. Keep your bedroom windows closed at night. Wearing several layers of clothing will keep you warmer than one thicker layer.”
Darren Clark, Severe Weather Resilience Manager at National Highways, said: “Gritters continue to undertake salt spreading over the coming days where needed during the first significant operation of this autumn and winter season on motorways and major A-roads amid colder temperatures across the country.
“National Highways is committed to treating every road which needs to be treated – whenever it is needed. We are armed with the latest technology, forecasting intelligence and years of experience to help us make informed decisions about where and when we need to spread salt to help keep road users safe in even the most adverse weather conditions.”
