PAGASA 00Z已经认定LPA，并认为其有中等可能性在未来24小时内发展为热带低压

As of 8:00 AM today, 04 May 2026, a Low Pressure area (LPA 05a) is being monitored outside the Philippine Area of Responsibility (PAR) and is "UNLIKELY" to develop into a tropical depression within the next 24 hours.
Meanwhile, another Low Pressure area (LPA 05b) is being monitored outside the Philippine Area of Responsibility (PAR). It has a "MEDIUM" potential to develop into a tropical depression within the next 24 hours.
All are advised to monitor updates from DOST-PAGASA.

1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED NEAR
7.5N 151.7E IS NOW LOCATED NEAR 7.9N 150.9E, APPROXIMATELY 67 NM WEST-
NORTHWEST OF CHUUK. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI)
DEPICTS A PARTIALLY OBSCURED LOW LEVEL CIRCULATION CENTER (LLCC) WITH
DISORGANIZED CONVECTION BEGINNING TO CONGEAL INTO FORMATIVE BANDS IN THE
SOUTHEASTERN SEMICIRCLE. A 032316Z PARTIAL ASCAT PASS REVEALS A WEAK,
CLOSED LLCC CENTERED IN THE VICINITY OF CHUUK, WITH MODERATE WESTERLIES
ALONG THE SOUTHERN FLANK AND MODERATE NORTHEASTERLIES TO THE NORTH.
ENVIRONMENTAL ANALYSIS DEPICTS A FAVORABLE ENVIRONMENT FOR DEVELOPMENT
WITH GOOD UPPER-LEVEL OUTFLOW PROVIDED BY AN UPPER-LEVEL POINT SOURCE IN
CLOSE PROXIMITY, LOW VERTICAL WIND SHEAR (10-15 KTS), AND WARM SEA
SURFACE TEMPERATURES (2930 C). BOTH GEFS AND ECENS DEPICT 93W TRACKING
WESTWARD OVER THE NEXT 24-48 HOURS AS IT SLOWLY CONSOLIDATES. THE
DETERMINISTIC MODELS ARE LAGGING BEHIND, INDICATING A SLOWER PACE OF
CONSOLIDATION AND PRIMARILY SUPPORTING A LATER WINDOW FOR
INTENSIFICATION. THE ECMWF IS THE SOLE DETERMINISTIC MODEL DEPICTING 93W
REACHING TROPICAL DEPRESSION STRENGTH WITHIN THE NEXT 48 HOURS. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 13 TO 18 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS
REMAINS LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
