1-DAY FORECAST OUTLOOK & ANALYSIS*

JELAWAT (LAWIN) is expected to continue accelerating rapidly NE-ward during the rest of the forecast period. On the forecast track, the core of JELAWAT is expected to make landfall over Southern Honshu this afternoon and will move over land, crossing the East Central part of Honshu tonight. It will then pass just north of Metropolitan Tokyo between 8-10 PM Japanese Time...and could be over Kuril Islands on Monday.

Maximum Sustained Winds (1-min. avg) have rapidly decreased to 120 km/hr (65 knots) with higher gusts. This typhoon will continue to decay during the next 24 hours as it moves into an area of lower Ocean Heat Content (OHC) or cooler sea-surface temperatures and moves across the Japanese landmass.

Tropical Storm Force Winds (62-117 km/hr) extend outward up to 280 kilometers (150 nautical miles) from the center. JELAWAT is a very large-sized tropical cyclone with a diameter of 945 kilometers (510 nautical miles) across.

The following is the summary of the 1-day forecast outlook on this system:

MONDAY NOON: Accelerating rapidly northeastward...passing over the Kuril Island Chain...weakens to a Tropical Storm (TS) as it becomes Extratropical...about 67 km South of Kuril Islands [12PM OCT 01: 43.9N 147.1E @ 75kph].

*Please be reminded that the Forecast Outlook changes every 6 hours, and the Day 3 Forecast Track have an average error of 250 km...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

Below is the summary of the storm's parts and its hazards affecting specific areas. You can also view this image link for you to understand the parts.

DISSIPATING EYE - over water (Sea south of Japan)...just along the southern shores of Kansai Region. Possible calm and lull conditions (with <20 kph winds) will be expected inside the eye (click here to know more about the EYE).
DECAYING EYEWALL - affecting Southern part of Kansai Region of Japan. Typhoon Conditions with Typhoon Force Winds (>118 kph) will be expected within this wall (click here to know more about the Eyewall).
INNER RAINBANDS - affecting and spreading across Southern Honshu. Tropical Storm Conditions with Tropical Storm Force Winds (62-117 kph) will be expected along these bands.
OUTER RAINBANDS - affecting and spreading across Kyushu, Shikoku, portions of Central Honshu and Sea of Japan. Cloudy/Rainy Conditions with moderate to strong winds (<62 kph) will 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 areas affected by the outer & inner rainbands (see above)...with isolated amounts of 101 to 200 mm (high to very high) along areas near the center of Jelawat (Lawin) (click to open NOAA's eTRaP graphic).
COASTAL STORM SURGE FLOODING - possible 4-5 ft (1.2-1.7 m) above normal tide levels...accompanied by large and dangerous battering waves can be expected along the coastal, inland lakes and beach front areas of Shikoku and Southern Honshu.. Moderate damage is likely on this type of storm surge. Danger from Rip Currents or Rip Tides can be expected along the rest of the beach-front areas of Extreme Northern and Eastern Luzon, and Eastern Taiwan (click here to know more about Storm Surge).

Important Note: Please keep in mind that the above forecast outlook, effects-hazards, current monsoon intensity, & tropical cyclone watch changes every 6 to 12 hrs!
