Winds from 101 kph to 185 kph may be expected in at least 18 hours.PSWS No. 4 PSWS No. 4 – A very strong typhoon will affect the locality. Very strong winds of more than 185 kph may be expected in at least 12 hours.
Hazards associated with Hazards associated with TCTC
•Strong winds – immediate TC hazard to affect a community•Storm surge – due to winds of TC and the low pressure area
•Landslides – influenced by intensity of rains, soil characteristics, slope, land cover, infiltration, groundwater level, etc.
Hazards associated with Hazards associated with TCTC
•Floods and Flashfloods – due to rainfall volume, basin, & river characteristics, drainage problems, informal settlers, etc.

Procedure for Rainfall Procedure for Rainfall ObservationObservation
•Observation shall be done as Observation shall be done as follows: During normal days, follows: During normal days, no significant weather, every no significant weather, every 8AM & 5 PM; During times of 8AM & 5 PM; During times of
inclement weather (TC inclement weather (TC present, monsoon rains, etc.) present, monsoon rains, etc.) every hour or 3-hours; Special every hour or 3-hours; Special
observation whenever observation whenever necessary during a brief heavy necessary during a brief heavy
downpour, downpour, or even during normal or even during normal period if able to do soperiod if able to do so
•Always press the reset button after every observation. Log the data on the respective time-column & day-row of the observation form.
•If there’s no rainfall observed, do not leave blank insteadplace “0” corresponding to the time & day on the form. Do not force a data in the form if you werenot able to observe during that day. If unable to observe the rainfall atthe respective time just fill-in the accumulated data on the next-time column otherwise leave blank.
Procedure for Water Level Observation:Similar with rainfall
observation (8AM & 5PM on regular days & hourly or 3-
hourly during inclement weather)If not able to observe at the
specified time, leave it blank!
Maintenance
Clean the Rain Gage with Clean the Rain Gage with water every 6 months or water every 6 months or
whenever necessarywhenever necessary
Clean when there’s no rain. Do Clean when there’s no rain. Do not forget to reset the LCD not forget to reset the LCD
after cleaning the gage with after cleaning the gage with waterwater
Maintenance
Replace the LCD monitor Replace the LCD monitor button-type battery after a button-type battery after a
yearyearWash the water level gage Wash the water level gage after every flood event or after every flood event or
when there’s dirt on the gage when there’s dirt on the gage repaint whenever necessaryrepaint whenever necessary
