After this, Mindanao and the regions of MIMAROPA, Eastern Visayas and Central Visayas will have light to moderate rains and thunderstorms. The regions of Cagayan Valley, Ilocos, CAR, Central Luzon and Bicol will experience cloudiness which may bring rains or thunderstorms at the midst of the forecast period up to the latter part of the dekad. The rest of the country will have partly cloudy to cloudy skies with isolated rainshowers or thunderstorms.

Light to moderate winds will blow from east to southeast over Luzon during the early days of the dekadal period. After this, gradual shift to northeasterly direction of moderate to strong winds will prevail over Luzon. The rest of the country will have winds coming from east to northeast.

During the early days of the forecast period, the seaboards of the whole country will be slight to moderate. The coastal waters of Luzon will be moderate to rough at the midst of the forecast period.

Probabilistic Rainfall Forecast


PROBABILISTIC RAINFALL FORECAST


Forecasting rainfall or temperature in probabilistic terms is a way of expressing uncertainty in the future weather/climate. When numerical probability values are assigned to the forecast, it is a way of indicating the amount of uncertainty in the forecast. Rather than say "below normal this July", we can say "30% chance to be below normal this July" when we think less rain is not so likely; or we can say "70% chance to be above normal this July " when we think great amount of rain is likely. Assigning a numerical value – a probability – to the occurrence of rainfall event allows us to quantify the uncertainty.


A probability forecast estimates the likelihood of occurrence of a specific event, which must be fully defined for the forecast to be verifiable. Events are defined by a time period and a specific location.


Probabilities are usually stated either as a percentage, which may range from 0 ("The event will definitely not occur") to 100 ("The event will definitely occur"). Values between 0 and 100 represent the different degrees of uncertainty.
