9-DAY WEATHER FORECAST
 
GENERAL SITUATION:
TROPICAL CYCLONE WIPHA WILL MOVE IN THE GENERAL DIRECTION
OF LUZON STRAIT TODAY. IT WILL ENTER THE NORTHERN PART OF
THE SOUTH CHINA SEA AFTERWARDS AND INTENSIFY GRADUALLY,
EDGING CLOSER TO THE VICINITY OF THE COAST OF WESTERN
GUANGDONG. HOWEVER, THERE ARE STILL UNCERTAINTIES IN ITS
INTENSITY. UNDER THE INFLUENCE OF THE OUTER SUBSIDING AIR
OF WIPHA, THE WEATHER WILL BE PERSISTENTLY VERY HOT OVER
GUANGDONG TODAY AND TOMORROW. THUNDERY SHOWERS TRIGGERED BY
HIGH TEMPERATURES WILL ALSO AFFECT THE REGION. WIPHA IS
EXPECTED TO BRING HEAVY SQUALLY SHOWERS AND THUNDERSTORMS
TO THE COAST OF GUANGDONG AND THE NORTHERN PART OF THE
SOUTH CHINA SEA DURING THE WEEKEND TO EARLY NEXT WEEK. SEAS
WILL BE ROUGH WITH SWELLS. UNDER THE INFLUENCE OF A BROAD
TROUGH OF LOW PRESSURE, THERE WILL STILL BE A FEW SHOWERS
OVER THE COAST OF SOUTHERN CHINA MIDWEEK NEXT WEEK.
