Tropical Cyclone Bavi weakened to a depression and NASA's RapidScat instrument measured its waning winds from space.

On March 17 the RapidScat instrument aboard the International Space Station (ISS) measured Bavi's from 01:28 to 3:01 UTC. RapidScat data showed surface winds were strongest winds in the northwestern quadrant. Sustained winds were near 17 m/s (38 mph/61 kph) and weaker around the rest of the storm.

On March 18 at 0000 UTC (March 17 at 8 p.m. EDT), the Joint Typhoon Warning Center noted that Bavi's maximum sustained winds dropped to 25 knots 28.7 mph/46.3 kph). It was located near 15.8 north latitude and 132.8 east longitude, approximately 489 nautical miles northwest of Yap, and was moving westward at 6 knots (6.9 mph/11.1 kph).

Bavi is moving west and weakening. The Joint Typhoon Warning Center expects Bavi to dissipate sometime on March 19.
