How long will the cold weather last?

The cold weather health watch comprises five levels of response based on cold weather thresholds.

The thresholds have been developed to trigger an alert when severe cold weather is likely to significantly affect people's health.

The alerts take account of temperature along with other winter weather threats such as ice and snow.

The Met Office has issued a yellow, or Level 2, cold weather alert for Cornwall and the south-west.

This means alert and readiness, with forecasters saying there is a 70% chance of icy conditions.

The alert was issued from 6pm on Sunday and will now be in force until 9am on Wednesday.

"There is a 70% probability of severe cold weather between 0900 on Monday 20th Jan and 0900 on Wednesday 22nd January in parts of England.

"This weather could increase the health risks to vulnerable patients and disrupt the delivery of services.

"Please refer to the national Cold Weather Plan and your Trust's emergency plan for appropriate preventive action.

"This cold weather alert extends the duration of the current cold spell to include Tuesday night into Wednesday morning, with frost and freezing fog patches again likely in the south of England in particular.

"These may prove slow to clear or perhaps persist in places to suppress daytime temperatures and help reach the mean of 2 degrees Celsius criterion.

"The second half of the working week should see cloud-cover and temperatures gradually increase, with further alerts not expected at this time".
