TROPICAL DEPRESSION Perla may brings rains over the provinces of Batanes, Apayao, and Cagayan, including the Babuyan Islands, starting Friday evening, weather bureau PAGASA reported on Thursday. Perla, with maximum sustained winds of 45 kilometers per hour (kph) near the center and gustiness of up to 55 kph, is not expected to intensify into a tropical storm. No storm signals were raised as of Thursday, but PAGASA warned that sea travel “is risky, especially for small sea vessels, over the northern and western seaboards of Northern Luzon due to potentially rough sea conditions associated with the northeasterly surface windflow.” As of 10 a.m. Thursday, Perla was 1,120 km east of Casiguran, Aurora and was moving west-northwest at 20 kph.
