Met Office Issues Yellow Weather Warning for Heavy Rain in Wales on Monday

The Met Office has issued a yellow weather warning for rain in most parts of Wales on Monday.


The warning will be in effect from midnight on Sunday until 9pm on Monday, August 13.

Heavy and persistent rain is anticipated to impact the country during this period.

Rainfall Development and Impact

According to the detailed warning, rain is expected to develop across southwest England and south Wales on Sunday evening.

This rain will then spread northeastward, affecting various regions of England and Wales throughout Monday.


The intensity of the rain is expected to vary, with a corridor of heavy, persistent, and possibly thundery rainfall forming within the broader band of precipitation.

While there is some uncertainty about the exact path of the heaviest rain, the warning indicates that many areas within the affected region can expect to receive 20-40 mm of rain.

Some places could even receive 60-80 mm, much of which might fall within a short period of 3-6 hours.

Northwest Wales and northwest England are currently predicted to experience the heaviest downpours.

Weather Outlook and Implications

Despite these improvements, the weather is still a departure from the typical expectations for August.
