FORECAST OUTLOOK ANALYSIS (up to 24 hours)*
SONGDA (CHEDENG) is forecast to continue losing its tropical characteristics as it passes along Southern Japan within the next 12 to 24 hours and will become Extratropical as it moves out into the cooler waters of the North Pacific Ocean.
Maximum Sustained Winds (1-min. avg) have decreased to near 95 km/hr (50 knots) with higher gusts. SONGDA (CHEDENG) is a Tropical Storm (TS) on the Saffir-Simpson Tropical Cyclone Scale. Tropical Storm Force Winds (62-117 km/hr) extend outward up to 230 kilometers (125 nautical miles) from the center. SONGDA is a large-sized tropical cyclone with a diameter of 775 kilometers (420 nautical miles).
*Please be reminded that the Forecast Outlook changes every 6 hours, and the Extended Forecast Track have an average error of 250 km on Day 3...450 km on Day 4...and 650 km on Day 5, while the wind speed forecast error, averages 35 kph per day. Therefore, a turn to the left or right of its future track and changes in its wind speed must be anticipated from time to time.
EFFECTS & HAZARDS SUMMARY CURRENT SW MONSOON INTENSITY: MODERATE >> Mostly cloudy with possible occasional rains w/ squalls can be expected along the following affected areas: WESTERN LUZON, WESTERN VISAYAS, PALAWAN, MINDORO, ROMBLON, MARINDUQUE, SOUTHERN TAGALOG PROVINCES including METRO MANILA & SUBIC BAY. Light to moderate SW to Westerly winds (not in excess of 40 kph) will blow.
SONGDA's circulation continues to decay as observed on satellite imageries. Below are the summary of the typhoon's parts and its hazards affecting specific areas: 
INNER RAINBANDS - off SW Honshu, Japan. Tropical Storm Conditions w/ Tropical Storm Force Winds (65-117 kph) can be expected along these bands. OUTER RAINBANDS - spreading across Rest of Honshu and Shikoku, Japan. 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 30 mm (low rainfall) can be expected along the outer & inner rainbands...with isolated amounts of up to 50 mm (medium) to the northeast of the center of SONGDA.

Important Note: Please keep in mind that the above forecast outlook, extended forecast, effects-hazards, current monsoon intensity, & tropical cyclone watch changes every 6 to 12 hrs!
JTWC (US NAVY & AIR FORCE) REMARKS:
REMARKS (for Meteorologists): 2 PM (06 GMT) SUN 29 MAY POSITION: 32.8N 134.2E.
*ANIMATED MULTISPECTRAL IMAGERY (MSI) SHOWS A FULLY EXPOSED LOW LEVEL
CIRCULATION CENTER (LLCC) WELL ALONG IN THE PROCESS OF EXTRA-
TROPICAL TRANSITION (XTT). THE POSITION CONFIDENCE IS HIGH DUE TO
THE FULLY EXPOSED LLCC, GOOD AGREEMENT BETWEEN AGENCY AND AUTOMATED
FIXES, AND RECENT MICROWAVE IMAGERY. ALTHOUGH THE UPPER LEVELS OF
THE STORM HAVE COMPLETELY SHEARED FROM THE LLCC, SURFACE REPORTS
FROM WAKAYAMA AIRPORT COUPLED WITH A 290004Z SSMIS PASS CONFIRM THAT
THE BOUNDARY LAYERS OF THE STORM REMAIN WELL ORGANIZED AND VIGOROUS.
THE CURRENT INTENSITY ANALYSIS IS BASED ON SURFACE REPORTS AND
DVORAK ESTIMATES FROM PGTW, RJTD, AND KNES. COMPUTER MODELS ARE
STILL STRUGGLING WITH THE INTERACTION BETWEEN THE TROPICAL SYSTEM,
THE BAIU BOUNDARY, AND A HIGH AMPLITUDE SHORT WAVE TROUGH MOVING
OVER WESTERN JAPAN. SOME VORTEX TRACKERS CONTINUE TO PULL THE LLCC
INLAND IN THE DIRECTION OF THE UPPER LEVEL HEIGHT FALLS, BUT MORE
MODELS, INCLUDING ECMWF AND NOGAPS, ARE BEGINNING TO RESOLVE THE
INTERACTION AND KEEP THE LLCC TRACKING EAST-NORTHEASTWARD. THE JTWC
FORECAST REMAINS TO THE RIGHT OF, AND FASTER THAN, CONSENSUS. TS 04W
IS EXPECTED TO TRACK THROUGH THE SOUTHERN PORTION OF WAKAYAMA
PREFECTURE AND THEN MOVE BACK OUT TO SEA, PASSING SOUTH OF BOTH
SHIMODA AND THE CHIBA PENINSULA. THE VIGOROUS UPPER LEVELS COUPLED
WITH THE BAROCLINIC BOUNDARY WILL KEEP TS 04W AT GALE FORCE THROUGH
THE ENTIRE XTT PROCESS...(more)
