Typhoon Hagupit – The Philippines

Saturday 06 December 2014

Typhoon Hagupit made landfall in the town of Dolores in the eastern Philippines, on Saturday afternoon (GMT). The storm brought down electricity lines and trees. Hagupit was weaker than originally anticipated, being reduced to a Category 3 storm, two levels below a “super typhoon”

VIDEO – Hagupit comes ashore with winds in excess of 120 km/h.

People were moved to higher ground and into more solid buildings such as churches, schools and sports stadiums. Dozens of domestic flights were cancelled and inter-island ferry services were suspended.

Public storm warning signals were applied in a number of provinces amid predictions winds could rip off roofs, cut power and damage buildings. Residents in low-lying areas were warned about possible flash floods and landslides.

Meanwhile, Google established a crisis page for Typhoon Hagupit to allow those in its path to track the storms progress

Hagupit, known locally as Ruby, had maximum sustained winds of 109mph and gusts of 130 mph when it made landfall in Dolores in Eastern Samar province on Saturday evening local time.

Sunday 07 December 2014

The wind strength at landfall made Hagupit the most powerful storm to hit the Philippines this year.

“Many houses, especially in the coastal areas, were blown away by strong winds,” Stephanie Uy-Tan, the mayor of Catbalogan, a city on Samar, told the AFP news agency. “Trees and power lines were toppled, tin roofs were blown off and there is flooding.”

Over 24 hours, the storm brought 396mm of rain, which is equivalent to half a month of precipitation.

Officials say two people were killed when the eastern provincial city of Borongan was hit by the storm.

Floods and landslides have already been reported in the nation’s central region, while four provinces have declared a state of emergency. Photos – Many remain in evacuation centres.

 

Monday 08 December 2014

As the typhoon weakened to a tropical storm and headed towards the capital Manilla, many have been preparing to return to their homes after the biggest peacetime evacuation in the countries history.

However, it appears that lessons have been learnt following the devastation caused by typhoon Haiyan last year when 7000 people died. Typhoon Hagupit has left around 22 dead.

Many put the reduced death toll down to the mass evacuation ordered by authorities after warnings were issued prior to the typhoons arrival on Saturday. Over one million people were moved to around 1000 emergency shelters across the country.

EFFECT ON DIFFERENT GROUPS OF PEOPLE AND THE ENVIRONMENT
Strong winds, floods and fallen trees have been causing chaos for travellers trying to get away for Christmas.
Many major roads were flooded or blocked by fallen trees, with Kent, Hampshire, Surrey, Sussexand Cornwallamong the affected counties.
In Dorset, 30 people trapped in cars by flood water were rescued by fire crews.
In Devon and Cornwall, several properties were flooded, while some homes are without power
In Newton Abbot, Devon, a man died after jumping into the River Lemon to rescue his dog. 
More than 6,000 homes without power in East Anglia, hundreds with no power in Somerset, and 50,000 homes in Hampshire and the Isle of Wight were cut off.
A man was taken to  hospital after being trapped under a fallen tree in St Martin, in Jersey.
The London Fire Brigade says it received five times the usual number of emergency 999 calls – 853 in total – on Monday night.
The severe weather caused disruption at some airports. At Gatwick, a power cut at the north terminal left several thousand passengers stranded, with delays and 26 flights cancelled.
Network Rail reported that the damage caused by the severe weather was “even more extensive” than that inflicted by St Jude’s storm in October.
