• 2019 North Indian Ocean cyclone season storm names

    Cyclonic-Storm-Pabuk-January-5-2019.jpg
    The list of the 2019 North Indian Ocean cyclone season unused storm names gets shorter. Yesterday, the third named storm of the season formed in the Arabian Sea.

    So far, the North Indian Ocean season goes like this. Cyclonic Storm Pabuk entered basin on January 4, followed byextremely severe Cyclonic Storm Fani (April 26 to May 4), and now Vayu heads towards India and Pakistan.

    Wait a minute, did I say 3rd? Then what's wrong with the infographic? Why Pabuk is missing? Nothing is wrong, it's just that Pabuk's name was assigned by the Japan Meteorological Agency, beause it entered the basin from the Gulf of Thailand.

  • Very severe cyclonic storm Vayu is not likely to make landfall on Gujarat coast
    • Update: Vayu is beginning to rapidly succumb to dry mid-level air and increased easterly vertical wind shear, weakening to tropical storm-equivalent strength. (Currently: 60 knots | 977 mbar)
    • Update: Cyclone Vayu likely to turn into depression, parts of North Guj may receive rain showers on June17, 18
    • Update: "It remains practically stationary in last one hour about 240 km West of Diu (Gujarat) and 130 km nearly South-West of Porbandar (Gujarat)," IMD said.

    • Update: Gujarat coast has narrowly escaped devastation, Vayu is located 130 km south of Porbandar, Gujarat. Max winds reaching 160 kph. Vayu is drifting away from Indian coast
    • Update: IMD has officially informed that the trajectory of Vayu cyclone has changed. Cyclone Vayu won't hit Gujarat. Still its effect will be seen on the coastal regions as there will be heavy wind speed and heavy rain.
    • Update: Vayu strengthened to Cat 3 Hurricane equivalent
    • Update: JTWC udated exposed population in cat 1 or higher from 490,000 to zero in it's latest estimates

    • Update: Cyclone Vayu is very likely to move nearly northwards and cross Gujarat coast as a Very Severe Cyclonic Storm with wind speed 145-155 kmph gusting to 170 kmph around morning of 13th June 2019.
    • Update: We've added impact estimates by JTWC, see below

    June 13th
    Vayu forecast

    June 12th
    300,000 people are set to be evacuated to shelter homes, fishermen have been advised not to venture into sea along and off the Gujarat coast till June 15.

    Vayu is likely to damage thatched houses, blow away rooftops and metal sheets, disrupt power and communication lines and cause major damage to roads and crops.

    June 11th
    Tropical Cyclone Vayu (VAYU-19, IMD's identifier ARB 01) formed 10 June 2019 in the Arabian Sea and it heads towards Gujarat and Pakistan, expected to strengten to Category 1 hurricane (or more precisely, because we are in the Indian Ocean basin, the Cyclone) later today (UTC 2019-06-11T18:00:00.000Z or 11 Jun 2019 8:00 PM local time).

    Extremely heavy rains are expected across coastal India and over Pakistan.

    Vayu is the 3rd named storm of the 2019 North Indian Ocean cyclone season.

    The outlook

    GDACS (JTWC) expects maximum wind speeds 167 km/h, estimate of the exposed population in Category 1 or higher is 6.6 million.

    Vayu formed early on June 10 as a tropical depression in the Arabian Sea, northwest of the Maldives, and it gradually strengthened, becoming a Cyclonic Storm Vayu later that day.

    Expected impact of the tropical storm Vayu

    Unlikely to be as destructive as Fani, tropical storm Vayu will still have a huge impact on India. GDACS (JTWC) estimates Vayu will affect the popullation of 3.5 million in Category 1 or higher, with 176 km/h maximum sustained wind speed, maximum storm surge 1.4 m (13 Jun 05:00 UTC), ranked as High vulnerability for India.

  • RE: New Windy "sounding" plugin - I suspect wrong speed (units??) in vertical speed profile

    That's probably something we can try.

    The thing is that different model report different things.
    I think that EC has all of model elevation, actual elevation and sfc temp while GFS only has actual? elevation.

    I have chosen to use the model elevation when available because what's below probably do not make a lot of sense ?

    hurricane-prep-week-boat-owners-advice.jpg

    WeatherNation has interviewed Charles Fort from Boat Owners Association about how the boat owners should prepare for the upcoming hurricane season, which begins this weekend.

    Many who live along the coast need to know what to do to secure their boat or vessel before a storm strikes. Boats can be greatly damaged, or cause damage to other property of if not properly secured or removed before a storm.

    Watch the video in which Charles Fort gives advice on what should the boat owners do.

    • Have a plan
    • If possible, take the boat out of the water
    • Never ride out the storm in your vessel

  • 2019 Atlantic Hurricane season outlook

    hurricane-michael-landfall_2018.jpg

    2019 hurricane season already began on May 15 for the Pacific Basin, and begins June 1 for the Atlantic basin.

    photo: Windy.com;link:;licence: cc;desc:2019 Atlantic Hurricane Season. Feel free to download the image and post it to your social media account, blog or website.

    The forecasts for both basins have already been released, including those from National Oceanic and Atmospheric Administration (NOAA) and Colorado State University.

    NOAA expects a “near normal” season for overall number of systems in the Atlantic basin (North Atlantic Ocean, Caribbean Sea, and Gulf of Mexico).

    NOAA provides these ranges with a 70% confidence. An average hurricane season produces 12 named storms, of which 6 become hurricanes, including 3 major hurricanes.

    NOAA's outlook for the 2019 Atlantic Hurricane Season indicates that a near-normal season has the highest chance of occurring (40%), followed by equal chances (30%) of an above-normal season and a below-normal season. The Atlantic hurricane region includes the North Atlantic Ocean, Caribbean Sea, and Gulf of Mexico.

    The 2019 outlook calls for a 70% probability for each of the following ranges of activity:

    • 9-15 Named Storms
    • 4-8 Hurricanes
    • 2-4 Major Hurricanes
    • Accumulated Cyclone Energy (ACE) range of 65%-140% of the median

    The seasonal activity is expected to fall within these ranges in 70% of seasons with similar climate conditions and uncertainties to those expected this year. These ranges do not represent the total possible ranges of activity seen in past similar years. These expected ranges are centered on the 1981-2010 seasonal averages of 12 named storms, 6 hurricanes, and 3 major hurricanes. Most of the predicted activity is likely to occur during the peak months (August-October, ASO) of the hurricane season.

    Above-normal 2019 Eastern Pacific and Central Pacific hurricane season

    In the eastern and central Pacific basins, NOAA expects a more active season as compared to normal with 5-8 named storms.

  • RE: New Windy "sounding" plugin - I suspect wrong speed (units??) in vertical speed profile

    @stitch good catch. The line was still potted with the wrong scale in unzoomed mode. This should be fixed in 0.8.5. (You can specify the version when loading the plugin using the name windy-plugin-soundig@0.8.5 before it becomes the default in a few hours).

    With regards to the scale in zoomed mode:
    The plugin is originally targeted to paraglider pilots.
    That's why I do not display hPa but elevation on the y axis and stop at ~7000m.
    Given that a paraglider fly at ~40km/h we are less interested in speed > 30km/h - we would start flying backward in gusts and also have turbulences.
    That's why having more granularity in the 0-30k range is interesting - we are only remotely interested in >30.
    It does not affect us that much: we wouldn't fly in that zone but knowing the max speed higher still could be interesting.

    That being said I'm open to extending the plugin for more use cases - we started discussing that with @johnckealy.
    What I do not want is to have to configure 20 different options to use the plugin but what I could imagine is to have a handful of different "profiles" (paragliding, meteo, ...) each having a sensible configuration.

    Having a shared google doc could help everybody interested share ideas ? Do you want to start one ?
