2026-05-18 05:16 AM SUMMARY: 10cm Radio Burst Begin Time: 2026 May 17 2050 UTC Maximum Time: 2026 May 17 2051 UTC End Time: 2026 May 17 2051 UTC Peak Flux: 370 sfu Duration: 1 minutes Latest Penticton Noon Flux: 104 sfu Comment: TROPICAL CYCLONE ADVISORY: ABPW10 PGTW 172000 MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI// SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH PACIFIC OCEANS REISSUED/172000Z-180600ZMAY2026// RMKS/ 1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA): A. TROPICAL CYCLONE SUMMARY: NONE. B. TROPICAL DISTURBANCE SUMMARY: NONE. C. SUBTROPICAL SYSTEM SUMMARY: (1) AN AREA OF CONVECTION (INVEST 98W) HAS PERSISTED NEAR 20.7N 130.6E, APPROXIMATELY 372 NM SOUTH-SOUTHEAST OF KADENA. THE SYSTEM IS CURRENTLY CLASSIFIED AS A SUBTROPICAL DISTURBANCE, GENERALLY CHARACTERIZED AS HAVING BOTH TROPICAL AND MIDLATITUDE CYCLONE FEATURES. ENHANCED INFRARED IMAGERY DEPICTS AN ILL-DEFINED LOW-LEVEL CIRCULATION PARTIALLY OBSCURED BY FLARING CONVECTION IN THE NORTHEAST QUADRANT AND SITUATED UNDER AN UPPER LEVEL LONG WAVE TROUGH. THE 170030Z ASCAT-B AND 171330Z OSCAT-3 PASSES REVEALED AN ASYMMETRIC WIND FIELD WITH 20-25 KNOT WINDS ON THE NORTHERN PERIPHERY OF THE DISTURBANCE. ENVIRONMENTAL ANALYSIS DEPICTS HIGH VERTICAL WIND SHEAR (25 TO 35KTS), WARM SEA SURFACE TEMPERATURES (28 TO 29 C) AND MODERATE POLEWARD UPPER LEVEL OUTFLOW AND DIVERGENCE. MODELS KEEP 98W UNDER THE TROUGH OVER THE NEXT 24-36 HOURS, AFTER WHICH TIME A STRONG RIDGE WILL BUILD IN FROM THE WEST AND INTRODUCE HIGH VERTICAL WIND SHEAR, AND VERY DRY AIR WILL ENVELOPE THE CIRCULATION. WHILE THE DISTURBANCE WILL REGAIN TROPICAL CHARACTERISTICS, THE DISTURBANCE IS UNLIKELY TO DEVELOP INTO A TROPICAL CYCLONE AS A RESULT OF THESE FACTORS OVER THE NEXT 36-48 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 28 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 IS LOW. (2) NO OTHER SUBTROPICAL SYSTEMS. 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. 3. JUSTIFICATION FOR REISSUE: ADDED AREA IN 1.C.(1) AS A LOW.// NNNN

1 Rain season in the Philippines: June 1st to Oct 31st.   5 Estimated amount of water needed to replace the water used by plants and evaporation from the past week. (Negative numbers mean amount of water needed, positive numbers mean excess water is present).   6 Air Quality Index is provided by Luftdaten System esp8266 and is updated every 5 mins..   9 Solar Index represents either an absolute scale of solar energy (W/m²) using the station’s recorded maximum or a percentage of computed theoretical solar maximum using the station’s location and time of day. These indices differ most when the sun is low on the horizon. The current scale is shown, and will toggle if it or the icon is clicked.   10 Historical average only to day 18 of just the month of May for this station since 2016.   11 Historical average rain this season to day 18 of May for this station since 2016.
