MUIFA's (KABAYAN) circulation remains intense with organized spiral band-convection on all sides. The typhoon's core is now showing a newly-formed large eye as a result of the Eyewall Replacement Cycle (ERC). Below is the summary of the storm's parts and its hazards affecting specific areas: LARGE EYE - over water (North Philippine Sea)...not affecting any land areas. Possible calm and lull conditions (with <20 kph winds) can be expected inside the eye (click here to know more about the EYE). NEW EYEWALL - over water (North Philippine Sea)...not affecting any land areas. Typhoon Conditions with Typhoon Force Winds (>118 kph) can be expected within this wall (click here to know more about the Eyewall). INNER RAINBANDS - over water (North Philippine Sea)...not affecting any land areas. Tropical Storm Conditions w/ Tropical Storm Force Winds (62-117 kph) will be expected along these bands. OUTER RAINBANDS - spreading & affecting Iwo To, Bonin & other nearby small islands. Tropical Depression Conditions w/ moderate to strong winds (25-61 kph) will be expected along these bands (click here to know more about Rainbands). 24HR TOTAL RAINFALL ACCUMULATION - from 5 up to 300 mm (low to high rainfall) can be expected along the outer & inner rainbands, affecting Bonin-Iwo To...with isolated amounts of up to 520 mm (very high) to the NE & near MUIFA's (KABAYAN's) center.

JTWC (US NAVY & AIR FORCE) REMARKS:
REMARKS (for Meteorologists): 8 AM (00 GMT) TUE 02 AUGUST POSITION: 22.3N 134.1E.
*TYPHOON (TY) 11W (MUIFA), LOCATED APPROXIMATELY 410 NM
EAST-SOUTHEAST OF KADENA AIR BASE, JAPAN, HAS TRACKED NORTHWARD AT
09 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS TY 11W HAS REFORMED AN EYE THAT IS COVERED BY A THIN
CIRRUS VEIL. THIS IS ALSO EVIDENT ON A 01/2109Z 91GHZ SSMIS IMAGE
THAT SHOWS DEEP CONVECTION CONTAINED IN THE NEWLY FORMED EYEWALL
STRUCTURE ALMOST COMPLETELY ENCOMPASSING THE LOW LEVEL CIRCULATION
CENTER (LLCC). THE DIAMETER OF THIS NEW RAGGED EYEWALL IS
APPROXIMATELY 13 NM, WHICH IS 6 NM LARGER THAN 12-HOURS AGO. UPPER
LEVEL ANALYSIS AND RECENT WATER VAPOR SATELLITE IMAGERY SHOW THAT TY
11W CONTINUES TO BE UNDER WEAK (05-10 KNOT) NORTHERLY VERTICAL WIND
SHEAR (VWS) AS THE SYSTEM HAS MAINTAINED A MESOSCALE ANTICYCLONE
ALOFT. EQUATORWARD OUTFLOW REMAINS EXCELLENT, BUT THE EASTWARD
OUTFLOW IS TEMPORARILY BECOMING DISCONNECTED FROM A TROPICAL UPPER
TROPOSPHERIC TROUGH (TUTT) CELL THAT IS FILLING INTO MID-LATITUDE
WESTERLY FLOW. HOWEVER, MULTIPLE TUTT CELLS THAT LIE FARTHER TO THE
EAST, NEAR THE DATELINE, ARE BEGINNING TO DEEPEN AND SHOULD RE-TAP
THE POLEWARD OUTFLOW CHANNEL OF TY 11W. THE INITIAL POSITION IS
SLIGHTLY SOUTH OF THE PGTW FIX POSITION BASED ON AN EXTRAPOLATION OF
A 01/1705Z AMSRE 37GHZ IMAGE. INTENSITY IS ALSO HELD HIGHER THAN
PGTW AND KNES DVORAK INTENSITY ESTIMATES OF 90 KNOTS TO MAINTAIN THE
FORECAST TREND AS THE NEW EYEWALL FORMS. TY 11W IS CURRENTLY
TRACKING NORTHWARD ALONG THE WESTERN PERIPHERY OF A NEAR EQUATORIAL
RIDGE CENTERED TO THE SOUTHEAST...more info)
