A health alert has been issued by the British officials, as the country supports itself for a heat wave this weekend.

Authorities are in the panic as the unusual high temperature of 31 degrees could leave people helpless to heat stroke.

This is UK's first weather health alert, which has been issued by the officials with temperatures, anticipated to reach 31 degrees across south-east England and East Anglia.

The Meteorology Office says that the major health threat will be the hot night time temperatures of at least 20 degrees in various places.

The National Health Service is recommending people on how to keep themselves and their houses fresh and cold. In the meantime, watering limitations have initiated in some parts of north-west England.

Met office has cautioned that tomorrow could be the hottest day of the year, so far with temperatures reaching as high as 90F or 32C.

The forecast has given rise to worries that health of the elderly, sick, young children and babies could be at large risk.

Analysts are predominantly concerned because there is likely to be no break from the heat when the sun sets with the mercury not sinking below 68F (20C) during the night.
