(CNN) -- A typhoon was expected to make landfall on the Philippines late Tuesday, CNN meteorologists say.

Tropical Storm Conson was producing 69 mph (111 kph) winds Monday. But the wind was forecast to pick up to 86 mph (139 kph), turning Conson into a typhoon. A typhoon of this size is similar to a Category 2 hurricane.

The typhoon was predicted to cause flooding and strong winds.

Authorities warned residents in Manila, the nation's capital, not to venture into the rain due to strong dangers posed by lightning.
