3-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 will pass over or very close to Amami Island before sunset...and could make landfall over Southern Honshu on Sunday evening. By Monday noon, JELAWAT is forecast to be passing just to the south of Kuril Islands.

Maximum Sustained Winds (1-min. avg) have decreased to 185 km/hr (100 knots) with higher gusts. This typhoon will continue to decay during the next 3 days as it moves into an area of lower Ocean Heat Content (OHC) or cooler sea-surface temperatures.

Typhoon Force Winds (118 km/hr or more) extend outward up to 130 kilometers (70 nautical miles) from the center...and Tropical Storm Force Winds (62-117 km/hr) extend outward up to 305 kilometers (165 nautical miles). 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 3-day forecast outlook on this system:

SUNDAY NOON: Accelerating rapidly northeastward...approaching the Southern Coast of Honshu...weakens to Category 1...about 100 km SE of Tanabe, Japan [12NN SEP 30: 32.9N 135.9E @ 130kph].
MONDAY NOON: Moving farther away from Japan, after crossing the main island of Honshu...downgraded to a Tropical Depression (TD)...about 278 km S of Kuril Islands [12NN OCT 01: 41.9N 146.9E @ 55kph].

*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.

14-KM PIN-HOLE EYE - over water (North Philippine Sea...just along the northern shores of Okinawa. Possible calm and lull conditions (with <20 kph winds) will be expected inside the eye (click here to know more about the EYE).
EYEWALL - affecting Okinawa. 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 Rest of Ryukyu Islands. Tropical Storm Conditions with Tropical Storm Force Winds (62-117 kph) will be expected along these bands.
OUTER RAINBANDS - affecting and spreading across Ishigaki Jima, Kyushu and Shikoku. 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 200 mm (low to high rainfall) can be expected along areas affected by the outer & inner rainbands (see above)...with isolated amounts of 201 to 305 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 9-12 ft (2.7-3.9 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 Okinawa and the Ryukyu today.. Extensive damage is likely on this type of storm surge.
