In emergencies, information saves lives. In Chuuk, #FSM 🇫🇲, the integrated OCHA/UNDAC team, with @IMMAP_inc and @mapaction, has been working with DECEM, Chuuk DCO, and IOM to turn data into decisions for the #TyphoonSinlaku response.

📢 Hurricane Melissa Update
In Kingston, WCK partner Mystic Thai prepared meals ahead of Hurricane Melissa’s arrival. Comforting plates of chicken curry with rice and salad were served to families sheltering from the storm. With our network of local partners, we’re ready to begin serving more meals as soon as it’s safe after Melissa’s landfall. #ChefsForJamaica
