     Besides the Observatory, the maximum temperatures at some other places of Hong Kong also rose to 36 degrees or above. They include Happy Valley, Sheung Shui, Wong Tai Sin, Tseung Kwan O and Sham Shui Po, with maximum temperatures soaring to 37.9 degrees, 37.8 degrees, 37.6 degrees, 37.6 degrees and 37.3 degrees, breaking their respective records. Figure 1 shows the maximum regional temperatures recorded today.

     Tropical cyclone Soudelor moved across the Taiwan Strait this afternoon. Under the influence of its outer subsiding air, the temperatures over Guangdong rose with little cloud amount. Temperatures over inland area reached 40 degrees or above. As northwesterly winds prevailed over Hong Kong today, the hotter air mass over Guangdong was brought to Hong Kong, leading to an extremely hot day. Satellite picture (Figure 2) indicates the influence of subsiding air (dark grey part) of Soudelor over Guangdong.

     In the case of August 18, 1990, weather of Hong Kong was fine, very hot and hazy under the influence of Typhoon Yancy as it moved towards Taiwan. The weather situation was similar to that of today and the maximum temperature recorded at the Observatory on that day was 36.1 degrees.
