TROPICAL CYCLONE WIND SIGNALS (TCWS) IN EFFECT
TCWS No. Luzon Visayas Mindanao
The eastern portion of mainland Cagayan (Santa
Ana, Lal-Lo, Gattaran, Baggao, Santa Teresita,
Gonzaga, Peñablanca), the eastern portion of Isabela
1 (Maconacon, Divilacan, Ilagan City, San Pablo,
Cabagan, Tumauini, Palanan, San Mariano, Dinapigue),
- -
Wind threat: and the northeastern portion of Catanduanes
Strong (Pandan, Bagamanoc, Panganiban, Viga)
winds Warning lead time: 36 hours
Range of wind speeds: 39 to 61 km/h (Beaufort 6 to 7)
Potential impacts of winds: Minimal to minor threat to life and property
OTHER HAZARDS AFFECTING LAND AREAS
Heavy Rainfall Outlook
Depending on how close it will be during its north northwestward movement over the Philippine Sea, the outer rainbands of
LEON may affect Extreme Northern Luzon. Furthermore, the trough of LEON may also affect the areas of Visayas, Mindanao,
and the western section of Southern Luzon. A Weather Advisory may be issued in the coming hours.
Severe Winds
The wind signals warn the public of the general wind threat over an area due to the tropical cyclone. Local winds may be
slightly stronger/enhanced in coastal and upland/mountainous areas exposed to winds. Winds are less strong in areas sheltered
from the prevailing wind direction.
Minimal to minor impacts from strong winds are possible within any of the areas under Wind Signal No. 1.
The highest Wind Signal which may be hoisted during the occurrence of LEON is Wind Signal No. 2 or 3, but this may still change
depending on how close the tropical cyclone will be during its north northwestward movement over the sea east of Batanes.
Furthermore, the wind flow coming towards the circulation of Tropical Storm LEON will also bring gusty conditions (strong to
gale-force) over the following areas (especially in coastal and upland areas exposed to winds):
Today (28 October): Batangas, most of MIMAROPA, most of Bicol Region, Visayas, most of Northern Mindanao, and
most of Caraga Region.
Tomorrow (29 October): Aurora, Metro Manila, CALABARZON, MIMAROPA, Bicol Region, Visayas, Dinagat Islands,
Surigao del Norte, and Camiguin.
Wednesday (30 October): Aurora, Metro Manila, CALABARZON, MIMAROPA, Bicol Region, Western Visayas, Negros
Occidental, and Northern Samar.

24-Hour Sea Condition Outlook
Up to very rough seas over the following coastal waters:
Up to 4.5 m: The seaboard of Batanes
Sea travel is risky all types or tonnage of vessels. All mariners must remain in port or, if underway, seek shelter
or safe harbor as soon as possible until winds and waves subside.
Up to rough seas over the following coastal waters:
Up to 4.0 m: The seaboard of Babuyan Islands and Isabela; the eastern seaboard of mainland Cagayan
Up to 3.0 m: The seaboards of northern Aurora and Camarines Norte; the remaining seaboard of mainland Cagayan;
the northern and eastern seaboards of Polillo Islands, Camarines Sur, and Catanduanes; the northeastern seaboards of
Northern Samar and Eastern Samar
Mariners of small seacrafts, including all types of motorbancas, are advised not to venture out to sea under
these conditions, especially if inexperienced or operating ill-equipped vessels.
Up to moderate seas over the following coastal waters:
Up to 2.5 m: The northern seaboard of Ilocos Norte; the remaining seaboard of Aurora and Northern Samar; the
northern and eastern seaboards of Quezon including the remaining seaboards of Polillo islands; the eastern seaboards
of Albay and Sorsogon
Up to 2.0 m: The remaining seaboards of the country.
Mariners of motorbancas and similarly-sized vessels are advised to take precautionary measures while
venturing out to sea and, if possible, avoid navigation under these conditions.
TRACK AND INTENSITY OUTLOOK
LEON is forecast to move westward for the next 12 hours before turning west northwestward tomorrow (29 October) early
morning. Considering the current movement, a further westward shift in forecast track is not ruled out. Afterwards, this
tropical cyclone may turn northwestward by Wednesday (30 October) until Thursday (31 October). LEON may make landfall
over Taiwan by Friday (1 November) early morning before turning north northeastward towards the East China Sea. On the
track forecast, LEON may pass closely over Batanes area by Wednesday or Thursday.
This tropical cyclone is expected to gradually intensify in the next 24 hours and may reach severe tropical storm category by
this afternoon. This tropical cyclone may also undergo rapid intensification.
Considering these developments, the public and disaster risk reduction and management offices concerned are advised to take all
necessary measures to protect life and property. Persons living in areas identified to be highly or very highly susceptible to these
hazards are advised to follow evacuation and other instructions from local officials. For heavy rainfall warnings,
thunderstorm/rainfall advisories, and other severe weather information specific to your area, please monitor products
issued by your local PAGASA Regional Services Division.
The next tropical cyclone bulletin will be issued at 11:00 AM today.
