Youth leader from Kay Kona at Watabung, Tennis Pepna, said the incident occurred around 3pm.
"It all happened within a minute but severe damages were caused. Fortunately, no one died,” he said.
The two victims were reportedly injured by falling trees. The child was admitted at Kundiawa Hospital while the woman is being treated at the nearby Watabung Health Centre.
The local said the whirlwind uprooted trees, damaged power posts and homes. The felled trees subsequently blocked off the road.
