MEGI is currently showing a 28-km clear eye...a sign that the howler is having an "explosive deepening" intensification. At 7:39 AM (23:39 GMT) this morning, a US Navy C-130 Reconnaissance Aircraft reported maximum outbound surface winds of 146 kts...270 kph, with a very low pressure of 908 millibars. The super typhoon is expected to continue moving westward across the Philippine Sea for the next 6 hours, before diving its track to the WSW through 48 hours. MEGI is forecast to continue intensifying...and will reach its peak strength of 270 km/hr tonight. The howler will be off the coast of Cagayan tomorrow morning as it prepares to make landfall [8PM OCT 17: 18.5N 125.1E @ 270kph...8AM OCT 18: 18.0N 122.9E @ 260kph]. The powerful core of MEGI (eye and eyewall) is now expected to make landfall over Southern Cagayan around noontime tomorrow...traversing the provinces of Cagayan...Apayao...Kalinga...Abra...and Ilocos Sur - Monday afternoon until early Tuesday morning. It will be downgraded to a Category 2 typhoon upon crossing Northern Luzon due to its interaction with the Sierra Madre and Cordillera Mountain Ranges [8PM OCT 18: 17.5N 120.7E @ 175kph]. Projected Landfall Area (Time): South of Escarpada Point, Northern Cagayan or along the Cagayan Mountains...about 55 km ENE of Tuguegarao City Monday noontime. MEGI will pass very close to Tuguegarao City tomorrow between 1-2 PM Monday...and will be about 15 km South of Vigan City, Ilocos Sur between 9-10 PM. It will be over the South China Sea...regaining strength by Tuesday morning [8AM OCT 19: 17.1N 118.3E @ 185kph].
Maximum Sustained Winds (1-min. avg) have rapidly increased to near 260 km/hr (140 knots) with higher gusts. MEGI is now a Category 5 Typhoon on the Saffir-Simpson Tropical Cyclone Scale...some strengthening is still likely prior to landfall over Cagayan tomorrow. Typhoon Force Winds (118 km/hr or more) extend outward up to 100 kilometers (55 nautical miles) from the center...and Tropical Storm Force Winds (62-117 km/hr) extend outward up to 270 kilometers (145 nautical miles). MEGI is a large-sized tropical cyclone with a diameter of 740 kilometers (400 nautical miles) across.
WEDNESDAY MORNING: Slows down while over the central part of the South China Sea...moving farther away from Luzon as it exits PAR...starts to turn WNW [8AM OCT 20: 17.2N 116.2E @ 195kph].
THURSDAY MORNING: Moving slowly WNW in the direction of Southern China (Western Guangdong)...still intensifying [8AM OCT 21: 17.7N 114.8E @ 205kph].
FRIDAY MORNING: Approaching the southern coast of Guangdong (just south of Hong Kong) with increased wind speed of 215 kph [8AM OCT 22: 18.8N 113.5E @ 215kph].
*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.
MEGI's core (eye and eyewall) and its rainbands continues to remain over the warm Philippine Sea...and are not yet affecting any major land areas at this time. Tropical Storm Conditions w/ Tropical Storm Force Winds will be felt across Northeastern Luzon, particularly Cagayan and Isabela beginning tonight or around midnight, Oct 18...turning into Typhoon Conditions throughout Monday (click here to view the latest NOAA-CIRA's Wind Analysis). 24-hr total rainfall amounts of 5 up to 150 mm (light to moderate rain) can be expected along its outer and inner bands...with isolated amounts of up to 350 mm (heavy) near the center of MEGI, especially along the northern portion (Click here to view the latest NOAA's eTRaP graphic on the storm's rainfall amount). Possible coastal Storm Surge flooding of more than 18 feet above normal tide levels...accompanied by large and dangerous battering waves...is possible along the coastal and beach front areas of Northern Luzon beginning tonight until tomorrow. Catastrophic 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 Eastern Luzon including Bicol Region.

*SUPER TYPHOON (STY) 15W (MEGI), LOCATED APPROXIMATELY 450 NM
NORTHEAST OF MANILA, PHILIPPINES, HAS TRACKED WESTWARD AT
12 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY AND A 162254Z SSMIS 91H MICROWAVE IMAGE DEPICT A WELL-
DEFINED 15 NM EYE WITH A CONCENTRIC EYE WALL AND EXCELLENT RADIAL
OUTFLOW. THERE IS HIGH CONFIDENCE IN THE CURRENT POSITION BASED ON
RJTD AND PGTW 17/00Z EYE FIXES. OVER THE PAST 12 HOURS, SUPER
TYPHOON MEGI HAS UNDERGONE RAPID INTENSIFICATION. THE CURRENT
INTENSITY IS BASED ON DVORAK INTENSITY ESTIMATES 0F 140 KNOTS FROM
PGTW AND RJTD, CIMSS SATELLITE CONSENSUS ESTIMATES OF 137 KNOTS AT
16/22Z, AND AN AIRCRAFT VORTEX MESSAGE AT 16/2339Z INDICATING
MAXIMUM OBSERVED SURFACE WINDS OF 120 KNOTS, MINIMUM SEA LEVEL
PRESSURE OF 908 MB (EQUIVALENT TO 153 KNOT VMAX ON THE KNAFF-ZEHR
SCALE), AND MAXIMUM OUTBOUND SURFACE WINDS OF 146 KNOTS. UPPER LEVEL
ANALYSIS REVEALS A SLIGHT WEAKENING IN POLEWARD OUTFLOW, HOWEVER
EQUATORWARD OUTFLOW INTO AN UPPER LEVEL LOW TO THE EAST REMAINS
VIGOROUS. THE TRACK HAS FLATTENED OUT AND STY MEGI IS NOW TRACKING

The only C-130 equipped to issue VORTEX messages are the WC-130Js of the 53rd Weather Reconnaissance Squadron Hurricane Hunters of the 403rd Wing of the Air Force Reserve Command of the USAF.
The only other aircraft equipped to issue VORTEX messages are the WP-3Ds of the National Oceanic and Atmospheric Administration of the US Department of Commerce.
The US Navy is no longer in the weather reconnaissance business.
