Put the beachwear away and dig the warm jackets back out – the city has been told to expect a rainy and cooler week following the first amber rainstorm warning of the year.

The amber alert, issued by the Hong Kong Observatory, lasted for about two hours yesterday.

Heavy rain and thunderstorms bore down on the city throughout yesterday, as citizens were also reminded to bring a jacket to keep warm as the temperature will drop from the highest of 28 degrees Celsius yesterday to the lowest point of just 19 today.

More than 2,000 lightning strikes were recorded during the storm. A thunderstorm warning was issued at 3pm, followed by the rainstorm signal at 3.20pm. All warnings were removed at about 5pm.

Last year, the first amber warning was issued in January, the earliest signal ever issued since the establishment of such system in 1992.

Usually the first rainstorm hits the city in April as the summer approaches, with more to follow when the city heats up.

The amber signal means heavy downpours exceeding 30mm per hour are expected to fall over Hong Kong. The Observatory said there would be flooding in some low-lying and poorly drained areas. It warned people to take necessary precautions and stay away from watercourses to avoid flash floods.

Yesterday’s weather was forecast to be 28 degrees Celsius, cloudy with showers and a few squally thunderstorms.

But the temperature began to drop to around 22 degrees Celsius after the sunset.

Moderate to fresh southerly winds, becoming northerly, will see temperatures fall to just 19 degrees today. Occasional showers should be expected throughout the weekend and it is likely that the wet weather will continue until the end of this month.
