During the "Undas", light to modearte rains is expected over Southern Luzon and Visayas tomorrow (31 October) and over the rest of Luzon including Metro Manila by Wednesday (01 November). This is due to the passage of a low pressure area (LPA) located east of Northern Mindanao moving west-northwest while embedded within the Intertropical Convergence Zone (ITCZ). The LPA upon crossing Visayas-Southern Luzon area from 31 October to 02 November (Thursday) is expected to develop into Tropical Depression before the weekend. Moderate to strong winds coming from the northeast is expected to prevail over Luzon and Visayas with moderate to rough coastal waters.

  • All travels and outdoor activities should be cancelled.
  • Evacuation to safer shelters should have been completed since it may be too late under this situation.
  • With PSWS #4, the locality is very likely to be hit directly by the eye of the typhoon. As the eye of the typhoon approaches, the weather will continuously worsen with the winds increasing to its strongest coming generally from the north. Then a sudden improvement of the weather with light winds (a lull) will be experienced. This means that the eye of the typhoon is over the locality. This improved weather may last for one to two hours depending on the diameter of the eye and the speed of movement. As the eye moves out of the locality, the worst weather experienced before the lull will suddenly commence. This time the very strong winds will come generally from the south.
  • The disaster coordinating councils concerned and other disaster response organizations are now fully responding to emergencies and in full readiness to immediately respond to possible calamity.
Preparation of Flood Forecast

The preparation, issuance and dissemination of an adequate and timely warning is the ultimate purpose of flood forecasting. Timeliness is an essential requirement for a flood warning. A sufficient lead time enables the ultimate user to take the necessary precautionary countermeasures.
 

         The hydrological and meteorological conditions in a river basin and the consequent state of its river system is never constant. The behavior of the river itself is the resultant of the interaction of all hydrological processes and conditions in the river basin.
 

         A flooding situation is not a daily occurrence. However, flood forecasting operations must, of necessity, be a continuous activity. It is carried out from day to day even when the possibility of a flood is highly improbable. This mode of operation enables flood forecasters to pinpoint the beginning of a potential flood-generating situation.
 

        Like storm bulletins which are issued only during the presence of tropical cyclones, flood forecast and warning bulletins are prepared only when a potential flooding situation is definitely present. They are issued regularly at specified hours of the day for the duration of the flooding period until the flood recedes or when all hazards and dangers associated with the phenomenon are no longer present.
 

       The prevailing hydrometeorological situation in a given river basin defines the operational environment under which flood forecasting and warning operations are carried out. Conveniently categorized into
 
  • normal situation,
  • alert phase, and
  • warning phase
these operational situations are dependent for their implementation on the behavior and state of the river with respect to a set of criteria known as flood assessment levels.

In practice1 flood bulletins are issued as soon as the development of a flooding situation exists. The initial bulletin serves merely to alert the people in the threatened basin to the possibility of a flood. It is never intended to categorically state that there will be flooding but only of the possibility. The initial bulletin is issued as soon as the operational situation passes from the alert to the warning phase. The transition from one operatiohal status to another is based on pre-determined criteria.

Thus, flood forecasting operation needs to be a continuing activity to determine the point in time when the operational situation passes from one phase to another. A flood forecasting operation consists of the following:

Monitoring:

This requires the collection, at regular interval, of the real-time data on rainfall, water level and other information that affect the hydrological condition of the river basin and the state of the river system. This provides a broad picture of the current situation in a river basin.

Analysis:


The data are analysed and related to other available information such as storm data from radar and satellite observation. The general objective here is to deduce the probable development in the hydrological situation in the river basin in the near future. This part of the operation involves a variety of hydrological analyses as well as the use of flood forecasting models to provide an objective estimate of the fore­cast situation.


Preparation of the forecast and warning:

Flood forecasts are completed in time for release at regular preset time of issuance. Dissemination is made through dissemi­nating agencies such as the OCD1 DSWD, NDCC, and thru the mass media, particularly radio and television.

There are three categories of flood information intended for the general public. All are issued under the general title of "Flood Bulletin". A distinct series of bulletins is issued for each threatened river basin where the forecasting and warning service is already extended and operational. As already stated, bulletins are issued only when conditions,

i.e., there is a potential flooding situation, so warrant their issuance.

When required, flood bulletins are prepared twice daily. They are completed and readied for issuance and dissemination at 5 a.rn. and 5 p.rn., respectively, when it is deemed early enough to provide vital information for concerned users to take necessary countermeasures before they leave for work in the morning or before they retire at night.

A series of bulletins for a given affected river basin is ideally initiated by a Flood Outlook. As the category implies, the bulletin merely states the present hydrological situation and alerts the people in a basin to the possibility of a deteriorating condition, e.g., a gradual and continuous rise in the water level.

Subsequent bulletins could be of any one of the three categories. Normally, for a given affected basin, one bulletin is followed by another of the same in the next higher category depending on the development in the hydrological condition and the forecast situation. Hence, an Outlook is followed by another Outlook or by a Flood Advisory; or by a Flood Warning.

When the situation had clearly reached its worst such that, at most the condition or, at best, improvement can be expected, subsequent bulletins are of the same or by a next lower category than the proceeding.

Upon receipt of the coded messages, they are decoded and each set of observations is plotted in symbols or numbers on weather charts over the respective areas or regions.  Observations made over land and sea are plotted on the surface or mean sea level charts which are prepared four times a day.  Radiosonde, theodolite, aircraft and satellite wind observations are plotted on upper level charts which are prepared twice daily.

Flood bulletins are specifically directed to the public. They are intended to apprise the people in the threatened area of the present situation and of the expected development. It suggests the appropriate actions the community may have to take to prevent or mitigate the disastrous effects of a flood.

  As in any kind of disaster, the best countermeasures for flood damage prevention and mitigation are those which are community efforts.

  Floods cannot be prevented. To a large extent, however, they can be controlled effectively. By this is meant keeping the river from overflowing. There are a number of ways of accomplishing this before and during a flood:
  • increasing the flow capacity of a river by cleaning the channel of debris, by dredging, by straightening of channels, etc.;
  • construction of dikes and levees; and
  • sandbagging during floods.
 When overbanking can no longer be avoided, flood control can take the form of directing floodwaters where it can do the least damage.
 Individually and collectively, people in a flood-stricken area must take precautionary measures to ensure personnel safety and health:

  1. People, particularly children, should avoid wading in floodwaters.
  2. Where houses are expected to be flooded, people should move to higher places.
  3. Electrically operated appliances should be transferred to upper storeys of buildings.
  4. When electrical fines and outlets will be submerged in floodwater, power should be switched off.
Flood damage mitigation and protection is a concern not only during the disaster. It should be practiced before, during and after the occurrence of a flood.   

Flood Safety Rules

    


BEFORE THE FLOOD:

  • Find out how often your location is likely to be flooded.
  • Know the flood warning system in your community and be sure your family knows it.
  • Keep informed of daily weather condition.
  • Designate an evacuation area for the family and livestock.
  • Assign family members instructions and responsibilities according to an evacuation plan.
  • Keep a stock of food which requires little cooking and refrigeration; electric power may be interrupted.
  • Keep a transistorized radio and flashlight with spare batteries, emergency cooking equipment, candies, matches and first aid kit handy in case of emergency.
  • Store supplies and other household effects above expected flood water level.
  • Securely anchor weak dwellings and items.
WHEN WARNED OF FLOOD:
  • Watch for rapidly rising flood waters.
  • Listen to your radio for emergency instructions.
  • If you find it necessary to evacuate, move to a safe area before access is cut off by flood waters.
  • Store drinking water in containers, water service may be interrupted.
  • Move household belongings to upper levels.
  • Get livestock to higher ground.
  • Turn off electricity at the main switch in the building before evacuating and also lock your house.
DURING THE FLOOD:
  • Avoid areas subject to sudden flooding.
  • Do not attempt to cross rivers of flowing streams where water is above the knee.
  • Beware of water-covered roads and bridges.
  • Avoid unnecessary exposure to the elements.
  • Do not go swimming or boating in swollen rivers.
  • Eat only well-cooked food. Protect leftovers against contamination.
  • Drink clean or preferably boiled water ONLY.
AFTER THE FLOOD:
  • Re-enter the dwellings with caution using flashlights, not lanterns or torchers. Flammables may be inside.
  • Be alert for fire hazards like broken wires.
  • Do not eat food and drink water until they have been checked for flood water contamination.
  • Report broken utility lines (electricity, water, gas and telephone) to appropriate agencies authorities.
  • Do not turn on the main switch or use appliances and other equipment until they have been checked by a competent electrician.
  • Consult health authorities for immunization requirements.
  • Do not go in disaster areas. Your presence might hamper rescue and other emergency operations
Flood are aggravated by factors resulting from the carelessness and indifference of people usually before floods occur.

THINGS ONE CAN DO TO MITIGATE FLOODS:

  • Regulate cutting of trees.
  • Report illegal loggers and kaingeros.
  • Report illegal construction of fishponds and other establishments in waterways.
  • Do not throw garbage in esteros and rivers.
  • Help clean the neighborhood.
  • Support community activities intended to lessen the occurrence of floods.
  • Avoid throwing anything like plastic wrappers anywhere which may clog or block the drainage system.

About The Satellites

HIMAWARI-8

The HIMAWARI-8 is a geo-stationary weather satellite, successor to Japan Meteorological Agency's Multi-functional Transport Satellite (MTSAT) series. It was installed at PAGASA last December 2015. It is the most utilized satellite imagery in real time weather forecasting , tropical cyclone analysis and for research purposes as it generates images every 10 minutes.


FY-2G FENGYUN CAST RECEIVING SYSTEM

The FY-2G receiver was installed in 2007 as a donation by the Chinese government to the Philippines. A geosynchronous meteorological satellite generating images twice per hour. It is used as a back up to the MTSAT in real time weather forecasting. Products are Composite, Infrared IR-1 and IR-2, Visible, Water Vapor.


COMS DATA ANALYSIS SYSTEM

The Communication, Ocean and Meteorological Satellite (COMS) is the first geostationary multi-purpose satellite of Korea which was launched in 2010. It was inaugurated at PAGASA in partnership with the Korea International Cooperation Agency (KOICA) in May 2017. Images generated every 15 minutes is used in weather forecasting and numerical weather prediction including cloud detection, estimation of radiation level in cloud-free region, land and sea surface temperature, fog detection, and rainfall intensity.

WEEKLY WEATHER OUTLOOK

26 May - 02 June 2023

 

 

 

Throughout the outlook period (26 May - 02 June), the expected entry inside the Philippine Area of Responsibility (PAR) of Typhoon MAWAR (2302) will trigger the southwest monsoonal flow to affect most parts the country in the next 7-day period.

 

At 12 noon today until tomorrow (26 - 27 May), Southern Luzon, Visayas and Mindanao will experience cloudy skies with scattered rainshowers and thunderstorms due to southwesterly flow triggered by Typhoon MAWAR (2302). The rest of the country will be partly cloudy becoming cloudy in the afternoon with rainshowers and thunderstorms.

 

By Sunday until Tuesday (28 - 30 May), Extreme Northern Luzon will be stormy as Typhoon MAWAR (2302) approaches while the rest of the country will be cloudy with frequent rainshowers and thunderstorms over southern Luzon and Visayas.

 

By Wednesday until Friday (31 May - 02 June), the whole archipelago will experience cloudy skies with frequent rains and thunderstorms particularly over the western section caused by the enhanced southwest monsoon. Flash floods and landslides is expected.

 

The updates on this Outlook will be through the daily issuances of the Public Weather Forecast and Weather Advisories if there are significant changes in the weather scenario.
