Level 3 Hot Weather Alert
There is a 90 % probability of Heat-Health Alert criteria being met between 1200 on Tuesday 09 Aug and 1800 on Saturday 13 Aug in London.
High pressure dominating this week, with fine and dry conditions across most of the country, prolonged sunny spells and light to moderate breezes. Temperatures rising from warm or very warm to locally hot in most regions, with a focus of the warmest weather in central-southern England. Headline max temperatures reaching mid 30’s by Friday. The biggest question mark is over the end of the hot spell, with recent models indicating thundery showers arriving from as early as Saturday 13th, but perhaps as late as Tuesday 16th. Confidence on this will likely increase later in the week.
An update will be issued when the alert level changes in any region. Alerts are issued once a day by 0900 if required and are not subject to amendment in between standard issue times. Note that the details of the forecast weather are valid at the time of issue but may change over the period that an alert remains in force. These details will not be updated here unless the alert level also changes, the latest forecast details can be obtained at the following link:
Advice: Look out for others, especially older people, young children and babies and those with underlying health conditions. Close curtains on rooms that face the sun to keep indoor spaces cooler and remember it may be cooler outdoors than indoors. Drink plenty of fluids and avoid excess alcohol, dress appropriately for the weather and slow down when it is hot.
