Cyclone Quartet Straddle the Pacific Ocean

8 08 2014

In the last few days a quartet of tropical cyclones have been active across the Pacific Ocean. For a period of time all four were simultaneously of hurricane intensity (winds greater than 74 mph). This is the first time this has happened in the Pacific Ocean for 12 years. Here we take a look at each of the storms and their likely impact.

Typhoon Halong formed near the US island of Guam and has been active in the west Pacific for over 10 days. It is now heading north towards south-western Japan and is set to bring strong winds and heavy rain this weekend to the area only recently affected by Typhoon Neoguri.

Typhoon Genevieve originated in the east Pacific and for a long time was a weak storm, even weakening to a remnant low pressure area at one stage. However, in the central Pacific Genevieve rapidly strengthened as it traversed an area of warm waters and gained hurricane status. As it crossed the International Dateline Hurricane Genevieve became Typhoon Genevieve. There is no difference between hurricanes and typhoons except that the former is used to describe tropical cyclones east of the Dateline and the latter to the west of the Dateline. Genevieve looks set to end its life as a tropical cyclone in mid-ocean well away from land.

Hurricane Iselle formed in the east Pacific just over a week ago. Iselle was downgraded to a tropical storm just as it made landfall over Hawaii today, but is still bringing strong winds, surf and heavy rain. Tropical storm or hurricane strikes directly over Hawaii are very rare. The last hurricane to make landfall over Hawaii was Iniki in 1992.

Hurricane Julio is following hard on the heels of Hurricane Iselle in the east Pacific and has become a ‘major hurricane’ with winds in excess of 115 mph.

 

Julio is also heading in the direction of Hawaii, but looks likely to track a little further north than Hurricane Iselle. However, the US state could still feel the affects of Julio as it passes by on Sunday.

Official warnings of west Pacific tropical storms are produced by the Japanese Meteorological Agency . Central Pacific warnings are issued by the Central Pacific Hurricane Center and east Pacific warnings by the US National Hurricane Center. The Met Office routinely supplies predictions of cyclone tracks from its global forecast model to regional meteorological centres worldwide, which are used along with guidance from other models in the production of forecasts and guidance.

Met Office StormTracker provides a mapped picture of tropical cyclones around the globe with access to track history and six-day forecast tracks for current tropical cyclones from the Met Office global forecast model and latest observed cloud cover and sea surface temperature.

Rain totals for 19th July 2014

20 07 2014

As forecast there were severe thunderstorms across the UK on the 19th July bringing heavy rain and gusty winds. See the tables below for the largest rain totals across the UK.  Gloucestershire recorded the highest rainfall with 66mm between 6am and 6pm yesterday, the counties monthly average rainfall is 60.6mm.

The Heat-health watch put in place in parts of southern and eastern England in conjunction with Public Health England has now been downgraded. Temperatures in parts of the area covered topped 28C during 19 July, see table below.

Today, 20 July, temperatures are expected to reach low to mid 20’s across central, south and south east of England, with London seeing around 27C.  Northern England will reach mid to high teens and Scotland and Northern Ireland mid to low teens.

More thundery downpours are expected to develop today over some eastern and central parts of the UK.  A yellow, be aware, weather warning for rain is in place for the areas likely to be affected. Not everywhere will see a storm but where they do occur, torrential downpours are possible with lightning, hail and strong gusts of wind. The areas most likely to be affected are across eastern and southeastern England.

Many places will have a good deal of fine and very warm weather this working week although there is the risk of some heavy showers in parts of the south and west later in the week.

Winds will slowly ease from tonight and we are expecting a brighter and less windy interlude over the course of Saturday and for most of Sunday with overnight frosts and sunny spells and a wintry mix of showers.

Another active atlantic frontal system is expected to swing eastwards across the country on Sunday night and Monday morning. A combination of strobng winds and moist air has the   potential to give locally significant amounts of rain which could cause the risk of further flooding.  The wind and rain are expected to clear eastward on Monday morning.

During this period of unsettled weather, people are advised to stay up to date with the latest Met Office forecasts and National Severe Weather Warnings and find out what to do in severe weather so they can plan ahead for the weather in store and make the most of the festive season. We would also encourage you to stay up to date with the latest news on flooding by checking the Environment Agency’s website for the latest flood alerts and warnings.

 





Stormy weather in the Mediterranean

15 11 2013

The central and western Mediterranean will experience very unsettled conditions through the weekend and next week.

Very heavy rain is expected to affect the northeast of Spain, southern France, the Balearic Isles, Corsica, Sardinia, Italy and the Adriatic facing Balkan nations as the very unsettled conditions move slowly east through the region.

Rainfall totals could be as high as 250mm in places, with a risk of up to 200mm in 24 hours. The average rainfall for November in this region is between 50mm and 100mm.

The rain will be associated with thunderstorms which could also produce hailstorms, very strong gusty winds and the possibility of tornadoes in a few places.

In addition to the rain, very strong winds are expected through the central and western Mediterranean, with widespread gales and a risk of storm force winds for a time. This will lead to rough seas that could pose a threat to shipping in the region.

There is also the risk of strong or gale force southeasterly winds affecting the Adriatic during Tuesday and Wednesday next week. These strong winds, combined with very heavy rainfall across the Venice region over the next few days could bring the risk of flooding in Venice.





Typhoon Haiyan makes landfall over the Philippines

8 11 2013

As predicted Typhoon Haiyan made landfall late yesterday evening (UK time) over the central Philippines.

Typhoon Haiyan will have caused catastrophic damage near the centre of its track through the Philippine islands of Samar, Leyte and Panay. In addition to the strong winds, the storm surge and heavy rain will also have caused major impacts in these regions. The typhoon is now moving out into the South China Sea. Over the next couple of days it is likely to lose some strength before making another landfall in northern parts of Vietnam on Sunday, although is still expected to be a typhoon.

At the time of landfall the estimated central pressure of the typhoon was 895 mb and sustained winds averaged over one minute estimated at 195 mph with higher gusts. These estimates are based on well attested satellite techniques, but without observations exactly in the path of the eye of the typhoon it is impossible to confirm their accuracy. However, this is likely to make Haiyan one of the most intense tropical cyclones to make landfall in history.

Forecast track of Typhoon Haiyan from the Japan Meteorological Agency.

In 1969 Hurricane Camille made landfall over the southern USA with sustained winds near 190 mph and in 1935 a hurricane which passed over the Florida Keys had an observed central pressure of 892 mb.

In terms of all time records, Typhoon Tip in 1979 holds the record for the lowest pressure in a tropical cyclone measured at 870 mb and the strongest wind gust ever recorded in a tropical cyclone was 253 mph in Cyclone Olivia off the north-west coast of Australia in 1996. As things stand these records seem likely to remain for the time being.

Regional warnings for Typhoon Haiyan are produced by the Japanese Meteological Agency (JMA) and the Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA). The Met Office routinely supplies predictions of typhoon tracks from its global forecast model to regional meteorological centres worldwide, which are used along with guidance from other models in the production of forecasts and guidance. Met Office model data and guidance is also used by Project NOAH in part for warning the government and the Filipino population.
