Tropical Storm Prapiroon intensified on Sunday before the center moved over Hainan.  Microwave satellite images indicated that an eye was in the process of forming at the center of Prapiroon’s circulation as the tropical storm made landfall in Hainan.  The formative eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the center of Tropical Storm Prapiroon.

Winds to tropical storm force extended out 70 miles (110 km) from the center of Tropical Storm Prapiroon.

The center of Tropical Storm Prapiroon made landfall on the south coast of Hainan near Lingshui.  The core of Prapiroon’s circulation moved across the center of Hainan.  Storms near the center of Tropical Storm Prapiroon brought heavy rain and strong winds to much of Hainan.  Bands in the northern part of Hainan’s circulation were also bringing gusty winds and heavy rain to parts of southern China.

Tropical Storm Prapiroon will move around the southern side of a high pressure system over southern China.  The high pressure system will steer Prapiroon toward the northwest during the next 24 hours.  On its anticipated track Tropical Storm Prapiroon will move over the Gulf of Tonkin on Monday.  The center of Prapiroon’s circulation could approach the southern coast of China in 24 hours.

Tropical Storm Prapiroon will continue to cause strong winds and locally heavy rain in Hainan during the next few hours.  Heavy rain could cause flash floods in some locations.  Prapiroon will also bring gusty winds and heavy rain to parts of southern China and northeastern Vietnam.
