RAINBANDS - over water (South China Sea), but with some of its scattered bands affecting Southern China Tropical Depression Conditions w/ moderate to strong winds (30-61 kph) can be expected along these bands (click here to know more about Rainbands).
24HR TOTAL RAINFALL ACCUMULATION - from 5 up to 100 mm (low to high rainfall) can be expected along the outer & inner rainbands...with isolated amounts of up to 250 mm (high) near the center of 06W (EGAY). (click to open NOAA's eTRaP graphic).

JTWC (US NAVY & AIR FORCE) REMARKS:

REMARKS (for Meteorologists): 2 AM (18 GMT) WED 22 JUNE POSITION: 19.0N 114.7E.
*TROPICAL DEPRESSION (TD) 06W (HAIMA), LOCATED APPROXIMATELY 200 NM
SOUTH OF HONG KONG, HAS TRACKED WEST-SOUTHWESTWARD AT 07 KNOTS OVER
THE PAST SIX HOURS. ANIMATED INFRARED IMAGERY SHOWS SIGNIFICANT
WARMING OF THE CONVECTION NEAR THE LOW LEVEL CIRCULATION CENTER
(LLCC), WITH DEEP CONVECTION REMAINING ALONG THE SOUTHERN PERIPHERY
OF THE SYSTEM. A 211742Z AMSU PASS SHOWS DEEP CONVECTION TO THE
SOUTH AND TO THE WEST WITH THE CENTER POORLY DEFINED AND DEVOID OF
CONVECTION. A 211302Z ASCAT PASS SHOWS 30KTS OF WIND TO THE SOUTH OF
THE LLCC BUT AT THE CENTER WINDS ARE RELATIVELY WEAK AT 15-20KTS.
UPPER LEVEL ANALYSIS SHOWS THE SYSTEM SOUTHEAST OF THE UPPER LEVEL
RIDGE IN AN AREA OF CONVERGENT FLOW AND MODERATE VERTICAL WIND
SHEAR. THIS APPEARS TO BE HAMPERING THE DEEP CONVECTION OVER THE
CENTER AND FURTHER DEVELOPMENT OF 06W. THE SYSTEM IS TRACKING ALONG
THE SOUTHERN PERIPHERY OF THE ASIATIC HIGH LOCATED OVER SOUTHEAST
CHINA. AS THIS HIGH MIGRATES TO THE EAST AND BECOMES ABSORBED BY THE
MID-PACIFIC HIGH, TD 06W WILL START TO GAIN LATITUDE AND MAKE
LANDFALL IN SOUTHERN CHINA..
