PAGASA says Emong (Co-may) might strengthen into a severe tropical storm on Thursday morning, July 24, and possibly into a typhoon before it makes landfall in the Ilocos Region
MANILA, Philippines – Tropical Storm Emong (Co-may) and Tropical Storm Dante (Francisco) both slightly intensified on Wednesday evening, July 23, while still enhancing the southwest monsoon or habagat.
Emong’s newly designated international name, Co-may, was contributed by Vietnam and refers to a kind of grass.
Emong
Emong now has maximum sustained winds of 85 kilometers per hour from the previous 65 km/h, said the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) in its 11 pm bulletin on Wednesday. The tropical storm’s gustiness increased from 80 km/h to 105 km/h.
PAGASA said Emong is now seen to strengthen into a severe tropical storm on Thursday morning, July 24, and possibly into a typhoon before it makes landfall.
As of 10 pm, Emong was located 235 kilometers west of Sinait, Ilocos Sur. It slowed down further, moving southwest at only 15 km/h from 20 km/h.
Several provinces in Northern Luzon will continue to see rain from the tropical storm in the next three days. Floods and landslides are likely.

PAGASA also raised Signal No. 2 due to Emong for the first time at 11 pm on Wednesday, and more areas were placed under Signal No. 1. Here is the full list of areas under tropical cyclone wind signals:
Signal No. 2
Gale-force winds (62 to 88 km/h), minor to moderate threat to life and property
- northwestern part of Pangasinan (Bolinao, Anda, Bani, Agno, Burgos)
Signal No. 1
Strong winds (39 to 61 km/h), minimal to minor threat to life and property
- Ilocos Norte
- Ilocos Sur
- La Union
- central and remaining northwestern parts of Pangasinan (Dasol, Alaminos City, Mabini, Labrador, Sual, Binmaley, Dagupan City, Lingayen, Bugallon, Infanta, Sison, Mangaldan, San Fabian, San Jacinto, Pozorrubio, Basista, Villasis, Malasiqui, Tayug, Urbiztondo, Bautista, Mapandan, Binalonan, Aguilar, Alcala, San Manuel, Asingan, Santo Tomas, Santa Maria, Urdaneta City, Laoac, Mangatarem, San Carlos City, Manaoag, Bayambang, Calasiao, San Nicolas, Santa Barbara)
- northern part of Zambales (Santa Cruz, Candelaria)
- Apayao

- western part of Nueva Vizcaya (Santa Fe, Bambang, Kayapa, Ambaguio, Bayombong, Solano, Villaverde, Bagabag, Diadi, Aritao)
The highest possible tropical cyclone wind signal due to Emong is now Signal No. 4, which is likely to be raised if it indeed reaches typhoon status prior to landfall.
The weather bureau expects Emong to follow a looping track over the West Philippine Sea on Thursday due to its “interaction” with Dante. Afterwards, it could make landfall in the Ilocos Region and pass close to Babuyan Islands.

Dante
Meanwhile, Dante’s maximum sustained winds increased from 65 km/h to 75 km/h, while its gustiness is now up to 90 km/h from 80 km/h.
“Further intensification into a severe tropical storm remains less likely but is not ruled out,” PAGASA said.
Dante was located 815 kilometers east northeast of extreme Northern Luzon as of 10 pm on Wednesday, staying far from land. It is moving northwest at a slower 15 km/h from 25 km/h.
This tropical storm is not directly affecting any part of the country, but its enhancement of the southwest monsoon continues.
Dante might leave the Philippine Area of Responsibility (PAR) on Thursday afternoon or evening as it heads for Japan’s Ryukyu Islands and the East China Sea.

In addition, PAGASA is still monitoring a low pressure area (LPA) outside PAR, located 1,980 kilometers east of Eastern Visayas at 10 pm on Wednesday.
The LPA still has a high chance of becoming a tropical depression within 24 hours. But the weather bureau said it appears unlikely to enter PAR. – Rappler.com
