According to the latest typhoon news from the US Joint Typhoon Warning Center (JTWC), Typhoon Grant may cause devastating strong winds, prolonged heavy rains, storm-induced sea level rise, very strong sea waves, landslides and flash floods.
Typhoon Grant is about 880 km south of Diego Garcia Island, moving west at a speed of about 26 km/h in the past 6 hours. Sea waves are up to 8.5 m high, causing great danger to ships and activities at sea.
This is a typhoon formed in the sea area between Indonesia and Australia from December 20. Typhoon Grant poured fierce thunderstorms as it approached the Cocos Islands (Keeling) in Australia right before Christmas.
The storm reached super typhoon intensity on December 29 and maintained wind intensity from 185-220km/h until the evening of the last day of 2025.
The storm has traveled a long distance across the Indian Ocean from the end of 2025 to 2026.
From the formation point near Christmas Island (Australian overseas territory), it is forecast that Typhoon Grant will move towards Madagascar and maintain a violent wind intensity of 120 km/h. The distance between these two locations is up to more than 6,300 km.
Forecast for January 1, 2026, Typhoon Grant will continue to move in a West-Southwest direction, dominated by subtropical high pressure in the Southeast.
After that, the storm may slow down temporarily, before another subtropical high pressure formation forms in the south, causing the storm to gradually move closer to the equator in the next 2-3 days.
In the first 2 days of the new year, Typhoon Grant tends to gradually weaken due to strong gusts of wind and dry air intrusion. Some typhoon forecast models may decrease to about 75 km/h, but JTWC assesses that the actual wind intensity may be slightly higher at a speed of about 150-165 km/h.
From about 3-4 days later, when atmospheric conditions are more favorable (winds break), Typhoon Grant is likely to strengthen again right at the end of the New Year holiday.
Tourists do not travel by boat, sea tourism or diving in the area affected by the storm in the Indian Ocean.
Tourists staying in Madagascar and neighboring islands should closely monitor local weather warnings and comply with evacuation instructions when necessary.
Proactively adjust travel schedules, avoiding coastal areas, low-lying areas prone to flooding, and areas at risk of landslides.
Regularly update weather information from local meteorological agencies and safety instructions from local authorities.
