The weather warning, which went into effect on Sunday, 18 June 2023, extends until 6 pm on Tuesday, 20 June.

These wave heights could reach between 6 and 8 meters from Cape Columbine to Plettenberg Bay into Tuesday morning.
This marine weather, coupled with gale to strong gale force westerly winds reaching speeds of 65 to 100 kilometres per hour, is expected to cause disruptions.
A Yellow Level 2 warning for damaging winds is expected over the Eastern Cape, valid from 10 am on Monday, 19th June until midnight on Tuesday, 20 June.
The passing cold front over the Eastern Cape, followed by ridging high pressure, may result in localised damage to settlements and infrastructure.
An additional Orange Level 5 warning for wind has been issued over the Northern and Western Cape, valid from midnight until 6 pm on Monday, 19th June.
The passing cold front is expected to generate gale force westerly to north-westerly winds, reaching speeds between 60 and 80 km/h and gusting up to 100km/h.
This will particularly affect coastal towns along the southwestern and southern coast, including Cape Town.
Potential impacts include structural damage to formal and informal settlements, disruptions to transport routes and travel services due to winds and falling trees, and power and communication interruptions.
High-sided vehicles on prone routes, such as the N2, may encounter difficulties.
