00:01Three different weather systems are still operating in our country.
00:05The first one is the North-East Monsoon or Hanging Amihan which is still warming.
00:09Here in a large part of Northern Luzon, the cold temperature is still increasing.
00:14The hot wind from Silangan, also known as the Eastern Lees,
00:18is affecting a large part of Visayas and Mindanao,
00:21and it is also causing rain in the eastern sections.
00:24And the third one is the Sheer Line.
00:26This is the line where the cold wind from Amihan and the hot Eastern Lees meet.
00:32And when this hot and cold wind is combined,
00:34there are chances of rain and thunderstorms.
00:37As can be seen in our latest satellite animation,
00:40there are continuous thunderstorms in some areas of Central and Southern Luzon.
00:44And based on our latest satellite animation,
00:47we do not see any typhoons entering our Philippine area of responsibility until the weekend.
00:54It will still rain in many areas of Luzon because it is still the North-East Monsoon,
00:58which is one of the Amihan,
01:00and it will bring mild to moderate rain here in the areas of Cagayan Valley
01:05and some parts of the Cordillera Administrative Region,
01:08such as Calinga, Apayao, Mountain Province, and Ifugao.
01:12So be careful of floods and landslides,
01:15especially in the areas of Cordillera and Caraballo Mountain Ranges.
01:20Meanwhile, here in some parts of the Cordillera Region,
01:24Benguet, Abra, Ilocos Region,
01:27and this left part of Central Luzon,
01:29Cabina ng Zambales, Bataan, Pampanga, and Tarlac,
01:32the sky is partly cloudy until the sky is cloudy,
01:35and it is still accompanied by mild to moderate rain effects of the North-East Monsoon.
01:41To our countrymen here in this part of Central Luzon,
01:44it is still expected that there will be heavy rains due to the shear line
01:48or the heat and cold winds of Aurora, Nueva Ecija, Bulacan,
01:54up to Metro Manila,
01:56a large part of Calabarzon, Camarines Norte, Camarines Sur,
02:00and the province of Catanduanes.
02:02So make sure that you have an umbrella if you are going out of your house.
02:05It is possible that there will be more or less 100 mm of rain
02:09that is moderate to heavy or intense rains at times
02:13in Quezon, Aurora, and Camarines Norte
02:16while we have moderate to heavy rains in other places
02:20that we have mentioned, but still be careful of flooding and landslides.
02:24In the remaining part of Luzon,
02:26including Mimaropa and the remaining part of Bicol Region,
02:30the sky is partly cloudy until the sky is still cloudy,
02:32and it is accompanied by mild to moderate rains or heat and cold winds.
02:36There is a high chance that it will reach the afternoon to the evening.
02:39In Metro Manila, the temperature is from 25 to 30 degrees Celsius,
02:43and due to the influence of the flood,
02:45our temperatures are also decreasing gradually
02:48in a large part of Northern and Central Luzon,
02:50and in Baguio, from 17 to 24 degrees Celsius.
02:54Our countrymen should also bring an umbrella
02:57to the eastern sections of Visayas and Mindanao
02:59because it will still be affected by the Easter Leaves
03:02or the wind from the east,
03:04Eastern Samar, Dinagat Islands,
03:06Surigao del Norte and Surigao del Sur,
03:08the chances of rain are high.
03:10Be careful of flooding and landslides.
03:14The remaining part of Visayas plus the Palawan area
03:17is partly cloudy until the sky is still cloudy in the morning,
03:20but the rain will also be expected
03:22when it reaches the afternoon to the evening,
03:24especially in the southern portions of Visayas.
03:26These are the areas of Southern Leyte up to Bohol,
03:30Southern Cebuat, and the eastern part of Negros Island Region.
03:34These are also the areas affected by the Volcano Canlaon.
03:39The rain will be expected there.
03:41Meanwhile, in the remaining part of Mindanao,
03:43it is partly cloudy until the sun is still shining in the morning,
03:46but there are also areas where it will reach the afternoon
03:48to the evening where there will be scattered rain and thunderstorms.
03:52These are the remaining parts of the Caraga Region and Davao Region,
03:56as well as the southern portions of Basilan, Sulu-Tawitawi,
04:00and the southern portion of Sok Sarjen.
04:02The temperature in Palawan is still possible to be a bit hot,
04:06up to 32 degrees Celsius.
04:08In a large part of Visayas, it is from 26 to 31 degrees Celsius.
04:13Meanwhile, here in Mindanao, it is from 25 degrees,
04:16but it is still the hottest in Zamboanga City and Cotabato,
04:19up to 34 degrees Celsius.
04:22For our fellow countrymen,
04:24we do not have a high-level gale warning
04:26because the winds are not that strong for now.
04:30But our waves here in the big town of Luzon
04:33plus the eastern seaboards of Visayas and Mindanao
04:36are a bit wavy, up to 3.4 meters,
04:38or it is on the floor of a house
04:40where the waves are high in a large part of the Caragatan.
04:43So be careful.
04:44It is still possible for our small sea vessels to be affected.
04:46The waves will be dangerous.
04:48But here in the remaining town of Visayas and Mindanao,
04:51the waves are moderate to moderate.
04:55And for our T-Day weather forecast,
04:57the effects of different weather systems are still there.
05:00Northeast monsoon here in Northern Luzon
05:03is still shearline in Central and Southern Luzon.
05:06Meanwhile, in the remaining part of the country,
05:08here in Visayas and Mindanao,
05:10sometimes it is easterly and there are times
05:12when the Intertropical Convergence Zone is still active
05:15or the wind waves from the Northern and Southern Hemispheres.
05:18In Northern Luzon, from Thursday to Saturday,
05:21the cold weather is still expected
05:23and it will be accompanied by mild to moderate rains
05:26in Cagayan Valley
05:27and a large part of the Cordillera Administrative Region.
05:30Only mild to moderate rains in Ilocos Region
05:33and the left part of Central Luzon.
05:35For our countrymen in Aurora,
05:37it is still there in Quezon
05:39and some parts of Camarines Norte, Laguna, Rizal,
05:42Aurora, Bulacan, Nueva Ecija,
05:45where there are still mild to moderate rains.
05:47At some point, until Thursday,
05:49it will be affected by the shearline or the winds
05:51of Amihan and Easterly.
05:53So make sure that we have an umbrella
05:55and still be careful of flood and landslides.
05:58And finally, here in the eastern sides of our country,
06:01in Visayas and Mindanao,
06:03as part of the Eastern Visayas,
06:04Caraga and Davao Region,
06:06there are scattered rains.
06:07Our rains are more frequent in those areas
06:10and in this part of Visayas and Mindanao,
06:13the rains will also be frequent
06:15from afternoon to night,
06:16from Thursday to Saturday.
06:18That is the effect of Easterly
06:19plus the Intertropical Convergence Zone.
06:22So it is always good for our rainfall advisories
06:24and even heavy rainfall warnings
06:26in a large part of our country.
