There is a 90% probability of Heat-Health Alert criteria being met between 0900 on Monday and 0900 on Friday in parts of England.
There is increased confidence that temperatures will rise through the weekend, becoming widely hot, locally very hot from Monday next week.
The highest confidence is for southeastern and eastern areas where temperatures are expected to reach the low 30s.
There is an increased confidence for thresholds to be reached across much of the Midlands, and perhaps eastern parts of southwest England and southern parts of the northwest England and Yorkshire and Humber regions.
Temperatures are likely to stay close to threshold through Wednesday, especially in for southern areas.
There is then uncertainty in maximum temperatures for later in the week and over the following weekend.
There is the potential for a brief dip in temperatures on Thursday and early Friday, although still feeling very warm, which may result in alert levels being reduced. This will be followed by a return to hot or very hot temperatures from late Friday 15th and into the following week.
This alert will be kept under review as confidence in the forecast increases.
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.
