Severe Tropical Storm Leon slows down east of Isabela

Severe Tropical Storm Leon (Kong-rey) is located 705 kilometers east of Echague, Isabela, as of 10 pm on Monday, October 28

MANILA, Philippines – Severe Tropical Storm Leon (Kong-rey) slowed down on Monday evening, October 28, “meandering” or wobbling over the Philippine Sea.

Leon was located 705 kilometers east of Echague, Isabela, as of 10 pm on Monday, slowly heading west after earlier moving at a speed of 15 kilometers per hour (km/h).

The severe tropical storm continues to have maximum sustained winds of 100 km/h and gustiness of up to 125 km/h.

The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) maintained in its 11 pm bulletin on Monday that Leon “is expected to rapidly intensify throughout its passage over the Philippine Sea,” and may strengthen into a typhoon within 12 hours, or by Tuesday morning, October 29.

“Furthermore, there is an increasing chance that Leon will reach super typhoon category during its period of closest approach to Batanes,” added PAGASA. This period may be on Thursday, October 31.

A typhoon has maximum sustained winds of 118 to 184 km/h, while a super typhoon has maximum sustained winds of 185 km/h or above.

There is still an “increasing possibility” of a further westward shift in Leon’s track, so the weather bureau is not ruling out landfall in Batanes, or a “close approach” to the province.

Leon’s trough or extension will continue to trigger rain in parts of Luzon and the Visayas, which may cause floods and landslides. Here is PAGASA’s latest rainfall outlook as of 11 pm on Monday:

Monday evening, October 28, to Tuesday evening, October 29

• Heavy to intense rain (100-200 millimeters): Cagayan including Babuyan Islands
• Moderate to heavy rain (50-100 mm): Batanes, Apayao, Ilocos Norte, Isabela, Calamian Islands, Occidental Mindoro, Negros Occidental, Antique

Tuesday evening, October 29, to Wednesday evening, October 30

• Intense to torrential rain (more than 200 mm): Batanes, Cagayan including Babuyan Islands

The highest possible tropical cyclone wind signal due to Leon is either Signal No. 3 or 4, “especially in extreme Northern Luzon.” But PAGASA is not ruling out the raising of Signal No. 5 if Leon reaches super typhoon status.
