Tropical Storm Irma: At the start of the summary period, Irma was moving
northwest with 45 kt winds. Irma turned north-northwest on 15 March while
slowly strengthening, and the storm reached a peak intensity of 60 kt on
16 March while recurving east-northeast. Irma rapidly weakened to a dep-
ression the next day while drifting northeast, and this general motion
continued until Irma dissipated near 20N 153E on 19 March. Although Irma
affected the Marshall Islands during its early stages, there are no reports
of damage or casualties at this time.
North Indian Ocean Basin: No tropical cyclones.
South Indian Ocean Basin (W of 135 Deg. E): No tropical cyclones.
South Pacific Ocean Basin (E of 135 Deg. E):

Roger was moving south off the east coast of Australia with 50 kt winds.
Roger continued south on 15 March while reaching a peak intensity of 60
kt. Roger continued southward the next day while slowly weakening. Cato
Island reported 41 kt sustained winds with a pressure of 986.5 mb at 2100
UTC 16 March. Roger started drifting northeast on 17 March, and this motion
continued through the next day. The storm turned east on 19 March, east-
southeast on 20 March, and southeast on 21 March. During this time, it
maintained 40-50 kt winds. At the end of the summary period, Roger was
moving southeast with 45 kt winds. There are no reports of damage or
casualties at this time.
Tropical Cyclone: A tropical depression formed near 18S 178W on 18
March. Accelerating southeast, this system reached tropical storm intensity
the next day. The cyclone became extratropical near 27S 158W on 20 March.
This system affected parts of the Fiji and Tonga Islands. Lifuka Island re-
ported sustained winds of 37 kt and a pressure of 996.7 mb at 0300 UTC 19
March. There are no reports of damage or casualties at this time. This
system may have been more like a monsoon depression than a true tropical
cyclone.
