Pdf | 618.14 Kb Tropical Cyclone Ula - Estimated Impacts Warning 22, 09JAN16 2100 UTC PDC - 06P - 22A [JTWC] Summary: TROPICAL CYCLONE (TC) 06P (ULA), LOCATED APPROXIMATELY 358 NM EAST-NORTHEAST OF NOUMEA, NEW CALEDONIA, HAS TRACKED SOUTHWESTWARD AT 06 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY SHOWED SIGNIFICANT INTENSIFICATION WITHIN THE CONVECTIVE CORE OVER THE PAST 6 HOURS WHICH SUPPORTS THE INCREASE IN INTENSITY TO 115 KNOTS. DVORAK INTENSITY ESTIMATES HAVE INCREASED TO T6.0 (115 KNOTS) FROM PGTW AND KNES. TC ULA IS ENCOUNTERING FAVORABLE ENVIRONMENTAL CONDITIONS WITH LOW VERTICAL WIND SHEAR (VWS), SEA SURFACE TEMPERATURES (SSTS) NEAR 27 CELSIUS, AND GOOD DIVERGENT OUTFLOW. THE CURRENT POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON THE 20NM EYE IN SATELLITE IMAGERY. FAVORABLE CONDITIONS OVER THE NEXT 12 TO 18 HOURS WILL SUPPORT CONTINUED INTENSIFICATION. THE CYCLONE IS TRACKING ALONG THE NORTHWESTERN PERIPHERY OF A DEEP-LAYERED SUB-TROPICAL RIDGE TO THE SOUTHEAST. NEAR TAU 24, TC 06P WILL REACH THE AXIS OF THE STEERING RIDGE AND TURN POLEWARD. AFTERWARDS, THE CYCLONE WILL ACCELERATE SOUTHEASTWARD WHERE IT WILL ENCOUNTER MODERATE TO HIGH VWS AND COOLING SSTS. THESE CONDITIONS WILL ERODE THE CORE STRUCTURE AND THE SYSTEM WILL RAPIDLY WEAKEN. TC ULA WILL FULLY DISSIPATE BY THE END OF THE FORECAST PERIOD AS IT INTERACTS WITH THE MID-LATITUDE WESTERLY FLOW. DYNAMIC MODEL GUIDANCE REMAINS IN TIGHT AGREEMENT WHICH SUPPORTS HIGH CONFIDENCE IN THE JTWC TRACK FORECAST.

  • Dear Friends
    REPORT 2016 Dear friends, 33 degrees Celsius, 93 Fahrenheit, summer in the South Pacific and somebody is dreaming of a White Christmas, time to write our report for this year. After our extensive travels last year, see Report 2015 , we had planned to stay here and tend to house and garden. The last cyclone season from November 2015 to April 2016 was characterized by a very strong El Nino effect, the predictions were for more and stronger cyclones to occure in Tonga, but until the end of the last year everything stayed calm. All our neighbors on the island were gone, the dog, cats and chickens crowding around us. We had a quiet Christmas and New Year's Eve, but on the first day of 2016 cyclone ULA approached and was supposed to pass by Vava'u with up to 115 knots (200 km/h-125mph). We put on the cyclone shutters, brought the boat into the sheltered Hunga Lagoon, took down the solar panels and secured everything. In the night, the storm passed through with howling winds and a lot of rain, but only a few old trees came down and some banana plants, no major damages. The next two weeks passed by with the usual activities in house and garden. It was pretty hot, which limited our activities somewhat, spiders and heron were still busy. On Thursday, January 14., we went into town to get supplies, in the evening we watched a movie at home. Then I noticed colorful flashes in my right eye when I moved my head fast.

In Tuvalu, households are acutely vulnerable to storm surges caused by cyclones even if the cyclone itself passes very far away (in this case about a 1000km). Based on a survey we conducted in Tuvalu, we quantify the impacts of cyclone Pam (March 2015) on households, and the determinants of these impacts in terms of hazard, exposure, vulnerability and responsiveness.

Based on a household survey we conducted in Tuvalu, we quantify the impacts of Tropical Cyclone Pam (March 2015) on households, and the determinants of these impacts in terms of hazard, exposure, vulnerability and responsiveness. Households experienced significant damage due to the storm surge caused by the cyclone, even if the cyclone itself passed very far away (about a 1000km). This risk of distant cyclones has been overlooked in the literature, and ignoring it leads to significant under-estimation of the disaster risk facing low-lying atoll islands. Lastly, we constructed hypothetical policy scenarios, and calculated the estimated loss and damage they would have been associated with – a first step in building careful assessments of the feasibility of various disaster risk reduction policies. Keywords: cyclone, Tuvalu, impact.

    MEDIA RELEASE No.2 st 4pm Thursday 31 December 2015 TROPICAL CYCLONE ULA AND TROPICAL DEPRESSION 07F At 1pm today, Tropical Cyclone Ula was located near 15.4 degrees South 167.8 degrees West or about 460km east-southeast of Apia and moving towards the southwest at 10 knots. Over the last 6 hours, TC Ula has slowly intensified and has developed into a Category 2 system with 50 knots winds expected close to its centre. It is expected to maintain a southwest track for the next 24 to 48 hours. On this projected path, it is expected to lie about 360km east- northeast of Vavau (Tonga) at 1pm tomorrow and about 180km northwest of Vavau at 1pm on Saturday. Tropical Depression (TD07F) was located near 14.9 degrees South latitude and 178.8 degrees East longitude or about 350km north-northeast of Nadi at 1pm today. It has a central pressure of 995hPa and accelerating as it is moving towards the southeast. On this projected path it is expected to pass to close to Fiji tomorrow. The system has low to moderate potential to develop into a tropical cyclone in next 24 to 48 hours. For Region: Strong wind warning remains in force for Tuvalu, Tokelau and Kiribati, Cook Islands and Niue. For Fiji: A HEAVY RAIN ALERT IS NOW IN FORCE FOR VANUALEVU, YASAWA AND MAMANUCA GROUP. Even though the global models together with the forecast track of Tropical Cyclone Ula indicates that it is approaching Fiji from the east, it is expected weaken to as it moves closer to the group.
