EFFECTS & HAZARDS SUMMARY
18W remains a tropical depression with convective rain clouds surrounding the circulation. Below are the summary of the depression's parts and its hazards affecting specific areas:
HEAVY SPIRAL RAINBANDS - its western rainbands continues to affect Central Vietnam...from the province of Quang-Tri down to Khanh Hoa...extending across Southern Laos. Where light, moderate to strong winds (<45 kph) can be expected along these bands today. (click here to know more about Rainbands).
12-HR TOTAL RAINFALL ACCUMULATION - from 5 up to 150 mm (light, moderate to heavy rain) can be expected along the rainbands...with isolated amounts of up to 230 mm (heavy) near the center of 18W, particularly along Bin Dinh, Quang Ngai & Kon Tum Provinces [click to open NOAA's eTRaP graphic].
CURRENT EASTERLIES INTENSITY: STRONG >> Partly sunny to mostly cloudy skies with passing rains, squalls (aka. "subasko") & thunderstorms can be expected along the following affected areas: NORTHERN QUEZON, BICOL REGION, EASTERN VISAYAS & EASTERN MINDANAO. Calm & light to moderate East, SE or NE winds (not in excess of 40 kph) can be expected today. The presence of strong easterlies (trade winds) are one of the signs of a strong La Nina climate occurring across the Pacific Ocean.
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!
