The tropical cyclone signal No.3 was issued at 14:00. Severe Tropical Storm “Ma-on” will quickly approach the western coast of Guangdong, closest to Macau from tonight to tomorrow morning(25th). It may intensify nearshore and pose considerable threat to Macao.
Under the influence of its outer rainband, the local weather will become unsettled in tonight. Winds will intensify, force of 7 - 9 with strong gust and frequent thundery showers.
The Yellow Storm Surge Warning was issued at 11:00. Under the combined influence of the storm surge and persisted rain, flooding is expected to occur in low-lying and coastal areas from 04:00 to 12:00 tomorrow. Since“Ma-On” may further intensify and flooding level may exceed 1.0 meter, the possibility of issuing orange storm surge warning remains relatively high. Public are advised to take precautions against wind and flooding as soon as possible.
Remarks: The probabilities of issuing severe weather warning signals for the next one or two days are provided in the table. Public can learn the possibility of being affected by the tropical cyclone over the specific period of time in Macao so that necessary precautions can be well prepared earlier.
