Typhoon Glenda (Rammasun-international code name) Forecast
Heavy rain will total 100-200 mm (4-8
inches) along and near the track of the storm, including
the cities of
Naga and Manila where flooding will be a serious concern. Floods are one of the most common hazards in the Philippines, however not all floods are alike.
Some floods develop slowly, while others
such as flash floods, can develop in just a few minutes and without
visible signs of rain. Additionally, floods can be local, impacting a
neighborhood or community, or very large, affecting entire river basins
and many provinces.
Flash floods can occur within a few
minutes or hours of excessive rainfall, or a dam or levee failure. Flash
floods often have a dangerous wall of roaring water carrying rocks, mud
and other debris. Overland flooding, the most common type of flooding
event typically occurs when waterways such as rivers or streams overflow
their banks as a result of rainwater or a possible levee breach and
cause flooding in surrounding areas. It can also occur when rainfall
exceeds the capacity of underground pipes, or the capacity of streets
and drains designed to carry flood water away from urban areas.

When crossing the Philippines, Rammasun
is expected to weaken due to the interaction with land and will likely
be a tropical storm as it emerges into the South China Sea. It will then
move across the South China Sea and will begin to make a gradual turn
to the northwest, towards the southern coast of China late in the week.
Moving over another area of very warm
waters and low to moderate shear will give Rammasun the opportunity to
regain typhoon strength before reaching China.
Late in the week, Rammasun will then
bring the threat for flooding rains and damaging winds to southern China
with the greatest impacts likely in Hainan and western Guangdong
provinces.

effects in the Philippines and, eventually, into China.
FLOOD ALERT:
Manila suffers severe flooding following torrential rainfall! Even if you feel you live in a community with a low risk of flooding, remember that anywhere it rains, it can flood.
