2026-05-26 08:35 AM ALERT: Proton Event 10meV Integral Flux exceeded 10pfu Begin Time: 2026 May 26 0010 UTC Noaa Scale: S1 - Minor Comment: NOAA Scale: S1 - Minor TROPICAL CYCLONE ADVISORY: ABPW10 PGTW 260600 MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI// SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH PACIFIC OCEANS/260600Z-270600ZMAY2026// RMKS/ 1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA): A. TROPICAL CYCLONE SUMMARY: NONE. B. TROPICAL DISTURBANCE SUMMARY: (1) THE AREA OF CONVECTION (INVEST 99W) PREVIOUSLY LOCATED NEAR 7.5N 141.7E IS NOW LOCATED NEAR 8.3N 138.5E, APPROXIMATELY 76 NM SOUTH- SOUTHEAST OF YAP. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 260001Z ASCAT PASS SHOW AN ELONGATED AREA OF TROUGHING WITH BROAD TURNING. THE LOW LEVEL CIRCULATION CENTER (LLCC) IS ASSESSED TO BE POSITIONED IN THE NORTHEASTERN END OF THE TROUGH. THE RADIUS OF MAXIMUM WINDS (RMW) IS MEASURED AT 150NM, WITH THE HIGHEST WINDS LOCATED TO THE SOUTH OF THE INITIAL POSITION. ENVIRONMENTAL ANALYSIS REVEALS A FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH MODERATE POLEWARD UPPER-LEVEL OUTFLOW, LOW TO MODERATE VERTICAL WIND SHEAR (10-15 KTS), AND WARM SEA SURFACE TEMPERATURES (29-30 C). THE PRIMARY DRIVER OF THE DEVELOPMENT TIMELINE IS THE SLOW CONSOLIDATION OF THE CURRENTLY HIGHLY ELONGATED CIRCULATION. GLOBAL DETERMINISTIC AND ENSEMBLE MODELS AGREE ON 99W TRACKING GENERALLY NORTHWESTWARD OVER THE NEXT 24-48 HOURS AS IT CONTINUES TO CONSOLIDATE AND INTENSIFY. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS MEDIUM. (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.// 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 26 of just the month of May for this station since 2016.   11 Historical average rain this season to day 26 of May for this station since 2016.
