A weakening Tropical Storm Erick was passing south of Hawaii on Friday.  At 11:00 a.m. EDT on Friday the center of Tropical Storm Erick was located at latitude 16.8°N and longitude 157.4°W which put it about 310 miles (505 km) south of Honolulu, Hawaii.  Erick was moving toward the west-northwest at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h).  The minimum surface pressure was 1000 mb.

An upper level trough northwest of the Hawaii Islands was producing strong southwesterly winds which were blowing across the top of Tropical Storm Erick.  Those winds were causing strong vertical wind shear, which was causing Erick to weaken quickly.  Most of the thunderstorms were occurring in bands northeast of the center of circulation.  Bands near the center and in other parts of Tropical Storm Erick consisted primarily of showers and lower clouds.  The stronger winds were occurring in the northern half of the circulation.  Winds to tropical storm force extended out about 100 miles (160 km) from the center of circulation.

A Flash Flood Watch was in effect for the Big Island of Hawaii through Saturday morning.  Counterclockwise flow around Tropical Storm Erick was producing southeasterly which were blowing up the slopes on the Big Island.  The enhanced rising will also increase rainfall on those slopes and flash floods could occur in some locations.

Elsewhere, Tropical Storm Flossie was showing signs of strengthening back into a hurricane.  An eye appeared to be forming at the center of Flossie.  At 11:00 a.m. EDT on Friday the center of Tropical Storm Flossie was located at latitude 17.1°N and longitude 137.8°W which put it about 1145 miles (1845 km) east of HIlo, Hawaii.  Flossie was moving toward the west-northwest at 17 m.p.h. (28 km/h).  The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h).  The minimum surface pressure was 993 mb.
