BoM編號29U

Tropical Low 29U
Tropical Low 29U to cross the north Queensland coast on Friday.
Forecast Track Maps and Severe Weather Warnings are being issued for Tropical Low 29U and should be referred to for further information.
Tropical Low 29U is currently located in the northern Coral Sea, northeast of Cairns.
It is expected to move southwest and cross the north Queensland coast on Friday.
It is unlikely that Tropical Low 29U will develop into a tropical cyclone before it crosses the coast.
Over the weekend there is uncertainty where the remnants of 29U will move as it weakens, with the most likely scenarios to either move west or to the southeast.

JTWC評級Low

AN AREA OF CONVECTION (INVEST 91P) HAS PERSISTED NEAR 16.9S
152.5E, APPROXIMATELY 150 NM EAST-SOUTHEAST OF WILLIS ISLAND. ANIMATED
ENHANCED MULTISPECTRAL IMAGERY (MSI) DEPICTS CYCLING DEEP CONVECTION
OVER A WEAKLY DEFINED LOW LEVEL CIRCULATION CENTER (LLCC), CONSISTENT
WITH THE 011811Z SSMIS 91 GHZ IMAGE. ENVIRONMENTAL ANALYSIS FOR THE
AREA INDICATES A FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH LOW
VERTICAL WIND SHEAR (10-15 KNOT), WARM SEA SURFACE TEMPERATURES (29-30
C), AND GOOD POLEWARD OUTFLOW ALOFT. GLOBAL MODELS ARE IN GOOD
AGREEMENT THAT 91P WILL CONTINUE TO MOVE NORTH-NORTHWEST WITH EXPECTED
GRADUAL INTENSIFICATION AS IT INTERACTS WITH THE SOUTH PACIFIC
CONVERGENCE ZONE OVER THE NEXT 48-72 HOURS. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 17 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1002 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.

JTWC評級提升至Medium

THE AREA OF CONVECTION (INVEST 91P) PREVIOUSLY LOCATED NEAR
15.2S 152.3E IS NOW LOCATED NEAR 14.9S 107.0E, APPROXIMATELY 140 NM
NORTHEAST OF WILLIS ISLAND. ANIMATED ENHANCED MULTISPECTRAL IMAGERY
(MSI) DEPICTS A QUICKLY CONSOLIDATING LOW-LEVEL CIRCULATION EMBEDDED
WITHIN A TROUGH, FEATURING DEEP CONVECTION BEGINNING TO DEVELOP NEAR
THE CENTER. A PARTIAL 022230Z ASCAT (METOP-B) PASS REVEALS STRONG
WINDS (20 TO 25KTS) ON THE NORTHERN PERIPHERY OF THE TROF AND 20-25
KTS ALONG THE SOUTHERN PERIPHERY, AND A STEADILY DECREASING RADIUS OF
MAXIMUM WINDS (RMW). ENVIRONMENTAL ANALYSIS DEPICT FAVORABLE
CONDITIONS FOR DEVELOPMENT WITH MODERATE VERTICAL WIND SHEAR (15 TO
20KTS), WARM SEA SURFACE TEMPERATURE (29 TO 30 C), AND GOOD POLEWARD
OUTFLOW. GLOBAL DETERMINISTIC AND ENSEMBLE MODELS ARE DEPICTING STEADY
DEVELOPMENT OF 91P AND A GENERAL WEST TRACK OVER THE NEXT 24 TO 48
HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 13 TO 18
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1009 MB. THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN
THE NEXT 24 HOURS IS UPGRADED TO MEDIUM.

SUBJ/TROPICAL CYCLONE FORMATION ALERT (INVEST 91P)//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
120 NM EITHER SIDE OF A LINE FROM 13.9S 150.8E TO 15.5S 147.3E
WITHIN THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY
ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME.
WINDS IN THE AREA ARE ESTIMATED TO BE 28 TO 33 KNOTS. METSAT
IMAGERY AT 031800Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 14.0S 150.7E. THE SYSTEM IS MOVING WEST-NORTHWESTWARD AT 10
KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 91P) PREVIOUSLY LOCATED NEAR
14.4S 151.7E IS NOW LOCATED NEAR 14.0S 150.7E, APPROXIMATELY 144 NM
NORTHEAST OF WILLIS ISLAND. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
DEPICTS A CONSOLIDATING LOW LEVEL CIRCULATION CENTER WITH CONVECTIVE
BANDING BEGINNING TO WRAP ALONG THE NORTHERN AND SOUTHERN SEMICIRCLES.
ENVIRONMENTAL ANALYSIS REVEALS A MARGINALLY FAVORABLE ENVIRONMENT FOR
DEVELOPMENT WITH MODERATE EQUATORWARD UPPER-LEVEL OUTFLOW, LOW VERTICAL
WIND SHEAR (10-15 KTS), AND WARM SEA SURFACE TEMPERATURES (29-30 C).
GLOBAL MODELS SHOW 91P TRACKING WESTWARD TOWARDS THE COAST OF AUSTRALIA
OVER THE NEXT 24-48 HOURS AS IT CONTINUES TO DEVELOP. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 28 TO 33 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 998 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS
IS HIGH.
