Tropical cyclones started as 1.
due to evaporation of water. It is developed from
the 2.
since Philippines is surrounded with water. In simple terms, a tropical cyclone is
system of3.
that are moving around the center. It is classified into four
categories: 4.
(64 kph), 5.
(118 kph), 6.
(200ph), and 7.
(>200 kph). As the winds intensify or weaken, the category is
upgraded or downgraded accordingly.
When a weather disturbance enters the 8.
the weather bureau begins to
monitor it. One thing about the tropical cyclone that we should watch out for is the strong winds. At the
of the tropical cyclone the wind speed is low. But in the dense cloud surrounding it, at the
10.
the wind speed is great.
When a tropical cyclone is on its way toward the land, public storm warning signals (PSWS) are issued
by 11.
to warn people about the approaching weather disturbance. A 12.
is
announced if a tropical cyclone has maximum winds of 30-60 kph which can be expected within 36
hours. A tropical cyclone is upgraded to PSWS #2 if the winds are greater than 13.
and may
be expected within 24 hours. When the tropical cyclone reaches a wind speed of 14.
the
signal is raised to PSWS #3. If the tropical cyclone intensified, 15.
is released by PAGASA
with very strong winds of more than 185 kph.
To be fully prepared for tropical cyclones, you should develop safety habits before, during and after
the tropical cyclone.
