Tropical Storm "IDAI 19" formed in the Mozambique Channel on March 9, 2019 as the
10th named storm of the 2018/19 Southwest Indian Ocean cyclone season. The
cyclone is expected to reach Category 4 hurricane equivalent and make landfall over
Mozambique coastlines Thursday, March 14. Tropical Cyclone IDAI is moving south-
southwest over the northern Mozambique Channel, strengthening. As of 11 March its
centre was located approximately 120 km north-west of Maintirano (Mahajanga
Province, western Madagascar) with maximum sustained winds of 167 km/h. IDAI is
now at such an intensity that she can have a high humanitarian impact as by GDACS
assessment. This is based on the maximum sustained wind speed, exposed
population and vulnerability.
Based on data of the expected tropical cyclone path IDAI, wind speeds zones from
Joint Research Centre (Issued on 12 March 2019 00:00 UTC), and population data
from WorldPop 2015, UNITAR-UNOSAT conducted a population exposure analysis
for Mozambique. About 6%, 3% and 10% of population of Mozambique living inside wind
speed zone of 120 km/h, 90 km/h and 60 km/h accordingly.
