People, including sea going vessels are strongly advised not to go out to sea until the system has moved out of the area. High Seas wind warning and a Marine strong wind warning are current for all coastal and open waters of Vanuatu. Very rough to phenomenal seas with heavy to phenomenal swells expected over northern and central open and coastal waters today as the system continues to move southeastward across the central part of Vanuatu. For detailed information, please refer to the Weather Radar Image website.Damaging gale force winds, destructive storm force winds and hurricane force winds with heavy rainfalls and flooding over low lying areas and areas close to the river banks including coastal flooding expected over TORBA, SANMA, PENAMA and MALAMPA Provinces and extending to SHEFA province today, including possible land slides. The Hong Kong Observatory's radar images closest to the time of tropical cyclone analysed position can be shown by pressing the 'Radar Image' button, below which is the 'Time of image' representing the time when radar completes its scan.Since it takes time to receive and process the satellite data as well as generate the image, the time of image may somtimes be different from the time of tropical cyclone analysed position. The infra-red satellite image closest to the time of tropical cyclone analysed position can be shown by pressing the 'Satellite Image' button, below which is the 'Time of image' representing the time when satellite data is completely received at the ground reception system.

The tracker also allows users to see the paths of previous hurricanes from this season, as well as interact with the satellite imagery. These departures are partly due to uncertainties in locating the centre of the tropical cyclone, and partly due to actual short-term variations in the direction and speed of movement of the tropical cyclone itself. Youve come to the right place The NOAA Hurricane Tracker shows active storms in the Atlantic or Eastern Pacific regions, monitored via the GOES East (GOES-16) and GOES West (GOES-17) satellites. Short-term erratic departure of the tropical cyclone from the general direction of movement may occur from time to time.The corresponding radius of 'Potential Track Area' is determined from the statistics in the past years as the mean value. In the Oval Office at lunchtime on Wednesday, Donald Trump held a briefing on Hurricane Dorian.At one point, the president held up a National Hurricane Center (NHC) map from 29 August, displaying. Such real-time positions could deviate from those obtained later through 'Best Track Analysis' when more comprehensive sets of observations become available.

*Analysed position refers to the positions of tropical cyclones fixed by the Observatory based on observation data available in real time. The size in terms of radius of the 'Potential Track Area' corresponding to different forecast hours are determined from the error statistics of the forecasts issued in past years (updated in 2022) and are as shown in the following table: Files are available under licenses specified on their description page. It will be particularly larger beyond 72 hours and is indicated with lighter shadings on the map. This page was last edited on 19 July 2021, at 10:15. The area grows as the forecast hour increases. Literally, it means that among 10 times of track forecast for similar situations, the tropical cyclone will be centred within the indicated area in about 7 times. By pressing the 'Potential Track Area' button, the probable area within which the tropical cyclone will fall with a probability of 70% will be shown.

While the forecast positions and track indicate the most likely future path of the tropical cyclone, they may deviate from the actual path of the storm.Please bear in mind the uncertainty of the tropical cyclone locations as described below in using this function. The user can use the controls on the left of the map to change the area of interest and to zoom into city or even street levels. With the search results, users can generate a map showing the track of the storm or storms accompanied by a table of related information. Detailed information of the tropical cyclone, including latitude, longitude, classification and the maximum sustained wind near centre will be shown when placing the mouse cursor over the analysed or forecast positions. Historical Hurricane Tracks allows users to search by place name, storm name or year, or latitude and longitude points.This gives you a detailed look at what's happening in the storm. *The tropical cyclone track, analysed positions and maximum sustained wind near centre are based on Hong Kong Observatory's tropical cyclone warning for shipping. Clime (previously called NOAA Weather Radar) is a good hurricane tracker app because it lets you overlay rain, radar, or satellite images on top of the tracker. the three radii represent the extent of Hurricane, Storm and Gale winds away.
