HEAT INDEX MONITORING AND FORECASTING (OBSERVED AND 5-DAY FORECAST)
The Heat Index is a human discomfort index that gives the apparent temperature on what humans perceive or feel as the temperature (from the surroundings) affecting the body. High air temperature and high relative humidity results to high apparent temperature. DOST-PAGASA issues Heat Index monitoring and forecast information which can be accessed online thru: https://bagong.pagasa.dost.gov.ph/climate/climate-heat-index
ENSO ALERT SYSTEM STATUS: EL NIÑO ADVISORY NO. 3 (updated as of 27 September 2023)
Moderate El Niño is present in the tropical Pacific and will strengthen further later in the year and will continue until the second quarter of 2024.
El Niño increases the likelihood of below-normal rainfall conditions, which could bring negative impacts (such as dry spells and droughts) in some areas of the country which may adversely impact the different climate-sensitive sectors which includes the water resources, agriculture, energy, health, public safety. However, over the western part of the country, above-normal rainfall conditions during the Southwest monsoon season (Habagat) may also be expected. Due to ongoing El Niño, enhanced Habagat is favored and may result in above normal rainfall conditions over the western part of the country.

During insufficient moisture supply, drip irrigation is one economical way of maintaining the moisture required by the crops. Mulching must be done to prevent the rapid loss of soil moisture and to maintain the good growing condition of crops.
IN AREAS AFFECTED BY SOUTHWEST MONSOON, TROUGH OF LPA, THUNDERSTORMS AND MODERATE TO HEAVY RAINS
Be alert and extra careful to those living in low lying areas and near mountain slopes due to possible flooding and landslides during moderate to heavy rains, Likewise extra caution in open areas for lightning strike. Farmers are reminded to do cover cropping, land terracing and waterway de-clogging activities. This is to prevent soil erosion and provide humus, regulate water, reduce weed, increase biodiversity and improve farming as a whole
