A Severe Weather Warning Bulletin for Northern and Central Vanuatu group issued by the Vanuatu Meteorology and Geo-Hazards Department, Port Vila. The warning noted “rain [is expected] with isolated heavy falls and thunderstorms over Northern and Central Vanuatu group. People are advised to take extra precautions for possible flash flooding; especially areas close to river banks and in low lying areas, and to remain indoors where thunderstorm activities are happening.”

Damaging winds and very rough seas with heavy swells will affect TORBA, PENAMA and SANMA. Heavy rainfall and flash flooding is also expected over low lying areas and areas close to river banks. Coastal flooding is also expected.

According to the Joint Typhoon Warning Center (JTWC), TC 18P has steadily intensified, and become increasingly organized, under the favorable influences of strong poleward outflow aloft, low wind shear…and passage over warm sea water.

TC Donna is expected to track westward to southwestward over the next 48 hours. At the same time, steady intensification is anticipated as environmental conditions remain favorable, with some guidance suggesting that a rapid intensification that currently being forecast.

Within 120 hours, increasing wind shear should initiate a weakening trend.

The current JTWC warning has consistently indicated a track running parallel and near the Vanuatu Island chain.

Maximum sustained winds as of the JTWC Warning #2 were 55 knots with gusts of 70 knots.
