Hong Kong is getting a very wet start to July, with at least 12 days of frequent showers and humidity of up to 95 per cent on the way, according to the Observatory. On Tuesday morning, many had to rush to work in heavy downpours, with occasional sunshine. The flag-raising ceremony at Golden Bauhinia Square was cancelled for the second day in a row. The Observatory issued its ninth thunderstorm warning in just the first four days of July at 2.35am on Tuesday, with some 740 lightning strikes in the first 10 hours of the day. The warning was still in force at midday, with temperatures around 30 degrees Celsius. The Observatory said rainy weather would continue to next Wednesday, with humidity above 70 per cent. Stormy Hong Kong weather blamed for slump in visitors to cable car Leung Yan-yu, a scientific officer at the Observatory, said she expected more thunderstorms from Thursday to Saturday, and that the weather in general would turn fine from Sunday. Leung advised Hongkongers to avoid outdoor activities, especially swimming and hiking, when thunderstorm warnings are in force.
