EFFECTS & HAZARDS SUMMARY
NOCK-TEN's (JUANING) circulation has started to deteriorate due to land interaction and increasing upper-level winds (Moderate Vertical Wind Shear). Below is the summary of the storm's parts and its hazards affecting specific areas: CENTRAL DENSE OVERCAST (CDO) - weakening while moving onshore off Northern Vietnam. (click here to know more about CDO). INNER RAINBANDS - spreading & affecting Northern Vietnam Tropical Storm Conditions w/ Tropical Storm Force Winds (62-100 kph) will be expected along these bands. OUTER RAINBANDS - spreading & affecting the Western Hainan, Central Vietnam, and Western Guangdong . Tropical Depression Conditions w/ moderate to strong winds (25-61 kph) will be expected along these bands (click here to know more about Rainbands). 24HR TOTAL RAINFALL ACCUMULATION - from 5 up to 150 mm (low to high rainfall) can be expected along the outer & inner rainbands...with isolated amounts of up to 200 mm (high) near the center of NOCK-TEN (JUANING). (click to open NOAA's eTRaP graphic). COASTAL STORM SURGE FLOODING - possible 0 to 3 feet above normal tide levels...accompanied by large and dangerous battering waves can be expected along the coastal and beach front areas of Northern Vietnam today. Minimal damage is likely on this type of storm surge. Danger from Rip Currents or Rip Tides can be expected along the beach-front areas of Central Vietnam, Hainan Island & Western portions of Guangdong Province.

JTWC (US NAVY & AIR FORCE) REMARKS:
REMARKS (for Meteorologists): 2 PM (06 GMT) SAT 30 JULY POSITION: 19.6N 106.8E.
*TROPICAL STORM (TS) 10W (NOCK-TEN), LOCATED APPROXIMATELY 100 NM
SOUTH-SOUTHEAST OF HANOI, VIETNAM, HAS TRACKED WESTWARD AT 11 KNOTS
OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
SHOWS CONVECTIVE BANDING WRAPPING INTO THE LOW LEVEL CIRCULATION
CENTER (LLCC) WITH DEEP CONVECTION SHEARING TO THE WEST. A 300634Z
AMSU MICROWAVE IMAGE SHOWS A LARGE CONVECTIVE BAND ALONG THE
SOUTHERN PERIPHERY. THE INITIAL POSITION WAS BASED ON THE MSI WITH
LOW CONFIDENCE DUE TO CLOUD COVER OBSCURING THE LLCC. THE INITIAL
INTENSITY WAS BASED ON PGTW AND RJTD DVORAK ESTIMATES RANGING FROM
35 TO 45 KNOTS AND A NEARBY SURFACE OBSERVATION OF 991MB. UPPER
LEVEL ANALYSIS INDICATES THE SYSTEM IS LOCATED IN AN AREA OF HIGH 30
KNOT VERTICAL WIND SHEAR. TS 10W IS EXPECTED TO MAKE LANDFALL OVER
VIETNAM WITHIN THE NEXT 12 HOURS AND THEN DISSIPATE OVER LAND.
NUMERICAL MODEL GUIDANCE IS IN GOOD AGREEMENT WITH THE WESTWARD
TRACK AS THE MAJOR STEERING INFLUENCE IS A STRONG RIDGE CENTERED TO
THE NORTH...(more info)
