• What is the Modified Public Storm Warning System?

• What is the importance of knowing the public storm warning

signals?

You have learned the tropical cyclones affect lives and

properties. People must be properly warned of the extent of the

damage brought about by the tropical cyclones.

Once a cyclone has developed, PAGASA begins giving

weather reports. As the cyclone is entering the PHILIPINE Area of

responsibility (PAR), PAGASA keeps people abreast by issuing

weather bulletins as often as necessary. These bulletins containinformation about public storm warning signals.



In the Philippines, there are four storm warning signals. This

system of warning signals was introduced in 1991 by PAGASA. The

system is called the Modified Public Storm Warning or MPSWS. In

this system, typhoon signal number 4 has been added to the originaltyphoon signal warning scheme. They are describe in the table on the

following page.

Table 10.6 Modified Public Storm Warning System

Signal Number Description

1 Winds of 30 – 60 kph are expected within 36 hrs. People should be

alert

2 Strong winds of 60 to 100 kph are expected within 24 hrs. Classes

in the Elementary and secondary levels are suspended.

3 Strong winds of 100 to 185 kph are expected within 18 hrs. classes

in all levels are suspended. Work in most government offices and

some private offices is likewise suspended.

4 Very strong winds more than 185 kph are expected within 12 hrs.



• The Philippine Atmospheric, Geophysical and

Astronomical Services Administration (PAGASA)

uses its own naming scheme for tropical cycloneswithin the Philippine Area of Responsibility,

regardless of whether it forms within or enters

from beyond. These unique identifiers are

usually local nicknames for people; should the

list of names for a given year be exhausted,

names are taken from an auxiliary list, the first

ten of which (i.e. those beginning in letter A-J)

are published every year. There are no names

that begin with the Filipino letters Ñ , NG and X .

Tropical Cyclone Intensity

Tropical cyclone intensity is defined by the maximum

mean wind speed over open flat land or water. This is sometimes

referred to as the maximum sustained wind and will beexperienced around the eye-wall of the cyclone.

Mean Winds and Gusts

Mean Wind: In most of the world the mean wind speed is

defined as the wind speed averaged over a period of 10

minutes. It should be measured at 10 m above the

surface. The major exception is the USA where they use a 1-minute average.

Wind Gust: In most of the world the wind gust speed is

defined as the wind speed averaged over 2 or 3 seconds (in

Australia we use 3 seconds).
