MUIFA's (KABAYAN) circulation remains intense with organized spiral bands convection on all sides, except for the NW portion. The typhoon's core continues to exhibit a small, cloud-filled eye surrounded by an inner and outer eyewall, which depicts an ongoing Eyewall Replacement Cycle (ERC). Below is the summary of the storm's parts and its hazards affecting specific areas: CLOUD-FILLED 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). INNER & OUTER 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 - over water (Philippine Sea)...not affecting any land areas. 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 250 mm (low to high rainfall) can be expected along the OUTER & INNER RAINBANDS...with isolated amounts of up to 350 mm (high) near the center of MUIFA (KABAYAN).

JTWC (US NAVY & AIR FORCE) REMARKS:
REMARKS (for Meteorologists): 2 PM (06 GMT) MON 01 AUGUST POSITION: 19.7N 134.1E.
*TYPHOON (TY) 11W (MUIFA), LOCATED APPROXIMATELY 525 NM SOUTHEAST OF
KADENA AIR BASE, JAPAN, HAS TRACKED NORTH-NORTHEASTWARD AT 09 KNOTS
OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY SHOWS
TY 11W NO LONGER HAS AN EYE AND THE CONVECTIVE EYE WALL HAS ERODED
ON THE NORTHERN SIDE. A 312306Z SSMIS 91H MICROWAVE IMAGE DEPICTS AN
OUTER CONVECTIVE RING SURROUNDING AN INNER HALF RING ADJACENT TO A
SUBSIDENT AREA. THIS INDICATES TY 11W IS UNDERGOING AN EYE WALL
REPLACEMENT CYCLE, WHICH HAS CAUSED TEMPORARY WEAKENING OF THE
SYSTEM OVER THE PAST 12 HOURS. THE INITIAL INTENSITY IS BASED ON
PGTW, KNES, AND RJTD DVORAK CURRENT INTENSITY ESTIMATES RANGING FROM
100 TO 115 KNOTS. THE INITIAL POSITION WAS BASED ON TIGHTLY CURVED
BANDING IN MULTISPECTRAL SATELLITE IMAGERY. UPPER LEVEL ANALYSIS
INDICATES A STRONG POLEWARD OUTFLOW CHANNEL TO THE NORTHEAST, GOOD
EQUATORWARD OUTFLOW, AND OUTFLOW INTO A TROPICAL UPPER TROPOSPHERIC
TROUGH (TUTT) CELL TO THE NORTHWEST. AN UPPER LEVEL TROUGH IS
LIMITING CONVECTION ALONG THE NORTHERN PERIPHERY OF THE SYSTEM. TY
11W IS CURRENTLY TRACKING IN A WEAK STEERING ENVIRONMENT BETWEEN TWO
DEEP LAYER RIDGES CENTERED TO THE SOUTHEAST AND CENTERED OVER
EASTERN CHINA. TY 11W IS EXPECTED TO TRACK MORE POLEWARD WITHIN THE
NEXT 12 HOURS. AS A STEERING RIDGE TO THE NORTH BUILDS IN, TY 11W
SHOULD BEGIN TO TURN NORTHWESTWARD TOWARD OKINAWA, JAPAN. NUMERICAL
MODEL GUIDANCE IS SPREAD IN THE TIMING OF THE TURN NORTHWESTWARD.
GFS AND GFDN ARE THE EASTERN OUTLIERS AND TAKE A WIDER TURN. THIS
FORECAST FAVORS A FASTER TURN NORTHWESTWARD AND HEDGES TO THE LEFT
OF MODEL CONSENSUS. TY MUIFA IS LIKELY IN A TEMPORARY STATE OF
WEAKENING DURING AN EYE WALL REPLACEMENT CYCLE. ONCE THE NEW EYE
WALL FULLY STRENGTHENS, TY 11W IS EXPECTED TO RE-INTENSIFY OVER THE
NEXT 36 HOURS. ADDITIONALLY, THE UPPER LEVEL TROUGH CURRENTLY TO THE
NORTH WILL TRANSIT NORTHWESTWARD AND ALLOW DEEP CONVECTION TO
DEVELOP ALONG THE NORTHERN PERIPHERY. AFTER TAU 48, OCEAN HEAT
CONTENT SHOULD DROP SIGNIFICANTLY AND CAUSE TY 11W TO SLOWLY
WEAKEN...more info)
