Cagayan Gov. Manuel Mamba canceled all classes from pre-school to senior high school in public and private schools in Cagayan.
Rogie Sending, officer-in-charge of the Cagayan provincial information office, said the declaration was based on a recommendation of the Provincial Climate Change and Disaster Risk Reduction Management Office (PCCDRRMO) to ensure the safety of students.
The Office of the Civil Defense (OCD) in Region 2 said “Kiko” accelerated slightly and moved in a northwest direction towars extreme Northern Luzon including the provinces of Cagayan, Batanes and the Babuyan Group of Islands.
The TCW signal previously raised in Ilocos Norte and Apayao were lifted also on Tuesday.
The typhoon maintained its strength and was expected to move northwest at 17 kph and move 55 km south-southwest of Basco, Batanes, on Wednesday morning and exit the Philippine Area of Responsibility by Thursday morning.

Magat Dam swells
The National Irrigation Administration-Magat River Integrated Irrigation System (NIA-MARIIS) in Cauayan City, Isabela, said the Magat Dam reservoir level may climb to its critical and spilling level.
This would be caused by downpour monitored by NIA-MARIIS with 1.6 millimeter in Banaue, 3mm in Halong (Ifugao), 2.0 mm in Dupax del Norte and 1.6 mm in Imugan, Santa Fe (Nueva Vizcaya).
NIA-MARIIS said the Magat Dam reservoir level reached 189.29 meters, which is 3.79 meters near its maximum and spilling level of 193 and .71 meter below its desired level of 190.
The swelling of the Ibulao River in Ifugao and the Magat River because of heavy downpour in Nueva Vizcaya has been a major cause of the rapid rise of the water level at the Magat dam.
Located at the border of Ramon, Isabela ,and Alfonso Lista, Ifugao, the rock-filled Magat dam built in 1983 also supplies irrigation water to approximately 85,000 hectares (210,000 acres) of farmland in Isabela and Quirino.
