A “blue moon,” or the second full moon of the month of July, will have occurred on Friday evening at 6:43 p.m., according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa).
Pagasa’s post early Friday said the lunar cycle is 29 days and most months have 30-31 days, thus, a full moon occurring at the start and end of the same month.
A full moon last occurred on July 2 at 10:20 a.m.
Pagasa said the phrase “blue moon” has nothing to do with the actual color of the moon, although a literal “blue moon” (the moon appearing with a tinge of blue) may occur under certain atmospheric conditions, such as volcanic eruptions or when exceptionally large fires leave particles in the atmosphere.
View of Friday’s rare “blue moon” may have been blurred by cloudy skies because of bad weather.
Based on Pagasa’s 24-hour public weather forecast issued at 5 a.m, there will still be Intertropical Convergence Zone across Mindanao.
Cloudy skies with light to moderate rains and isolated thunderstorms will be experienced over the Visayas and Mindanao and the provinces of Mindoro, Palawan, Romblon, Masbate and Sorsogon.
Partly cloudy to cloudy skies with isolated thunderstorms will prevail over Metro Manila and the rest of the country.
Meanwhile, light to moderate winds blowing from the northeast to north will prevail over Luzon and coming from the northeast to southwest over the rest of the country.
“The coastal waters throughout the archipelago will be slight to moderate,” Pagasa said.
Mindanao will experience cloudy skies with light to moderate rains and isolated thunderstorms.
Winds will be light to moderate coming from the northeast to southwest with slight to moderate seas.
In Northern Luzon, partly cloudy to cloudy skies with isolated thunderstorms will prevail over Aurora province, Cordillera, Ilocos Region and Cagayan Valley.
Light to moderate winds blowing from the northeast to north will prevail over Northern Luzon and the province of Aurora with slight to moderate seas.
Thunderstorms will prevail over the portions of Albay, Cebu, Leyte, Catanduanes, Negros Occidental and Negros Oriental, Bohol and the rest of Northern Mindanao.
“All are advised to take precautionary measures against heavy rains, strong winds, lightning and possible flash floods. Keep monitoring for updates,” Pagasa said.
