Cyclone (99P) INVEST is moving towards WSW at a speed of 16 km/h.

A cyclone generally forms over tropical oceans when the sea temperature exceeds 26°C at sufficient depth. Intense evaporation feeds warm, moist air that rises, creating a low-pressure area. Due to the Earth's rotation (Coriolis force), this system begins to spin and can intensify if atmospheric conditions remain favorable.

They are the same meteorological phenomenon: it is called a "cyclone" in the Indian Ocean and South Pacific, a "hurricane" in the North Atlantic and Northeast Pacific, and a "typhoon" in the Northwest Pacific. The difference is geographical.

The main dangers of a cyclone are: violent winds, heavy rains that can cause flooding, storm surge (very high waves), and sometimes landslides. It is important to follow the authorities' instructions and stay informed about the system's evolution.

Cyclone (99P) INVEST is currently generating average winds of 46 km/h and gusts up to 60 km/h.

To protect yourself from cyclone (99P) INVEST, follow official instructions: stay informed via weather bulletins, prepare an emergency kit, secure your home, avoid going out during alerts, and stay away from areas at risk of flooding or storm surge. Follow the advice of local authorities.

No major city is within 250 km of the cyclone center at this time.

The time of impact depends on the cyclone's track and speed. Check the track map and the estimated impact time shown above for your city or location. Stay tuned to official bulletins for updated forecasts.
