Hurricane Dorian, a Category 5 storm, hit the Bahamas in early September 2019. With winds of up to 220 mph and storm surges of up to 23 feet, it was one of the most powerful Atlantic hurricanes to make landfall.

The storm caused widespread flooding and destruction across Grand Bahama Island, killing at least 50 people and leaving over 70,000 people in urgent need of humanitarian assistance. Dorian was the first major hurricane of the 2019 Hurricane Season.

Soon after Hurricane Dorian made landfall, we sent a assessment team in the Bahamas.

Our teams conducted exhaustive research alongside IOM and the Red Cross, and met with our local Rotary contacts and other humanitarian agencies.

They visited the Abaco islands in order to understand the needs of people who had been affected the most, but didn’t find unmet emergency shelter needs.

Our teams are no longer in the country, but our work in the Bahamas will not stop. We’ll stay in contact with Rotary, the Government and with the other organisations who worked as part of the coordinated response. We will be ready to return if we have a part to play in future plans.

2019 Hurricane season

In an average season, there are 12 named storms, including six hurricanes, with about half of them being major hurricanes with winds of 111 mph or greater.In previous years over 80% of hurricane season activity has occurred during the two-month stretch from 20 August to 20 October.Each year, Colorado State University’s (CSU) Tropical Meteorology Project issues an updated outlook in order to account for the various summer changes. In August 2019 they predicted 14 named storms, seven hurricanes and two major hurricanes.Near-normal tropical storm activity was predicted for the Atlantic Ocean in 2019, according to NOAA, the National Oceanic and Atmospheric Administration.

Key facts about hurricanes

Open all

What exactly is a hurricane?

Hurricane and typhoons are cyclonic weather systems that form in the tropics and have sustained wind speeds of more than 74 miles per hour.

What’s the difference between a tropical storm and a hurricane?

Hurricanes, typhoons and cyclones are all tropical storms. The only difference is where they form. Hurricanes form in the tropical Atlantic and the Eastern Pacific.

Typhoons form in the West Pacific and cyclones form south of the equator, off the coast of places such as Australia and Madagascar.

How is hurricane strength measured?

The Saffir-Simpson scale is the standard scale for rating the severity of a hurricane as measured by the damage it causes.

It classifies hurricanes on a hierarchy from category 1 (minimal), through category 2 (moderate), category 3 (extensive), and category 4 (extreme), to category 5 (catastrophic). A super typhoon is equivalent to a category 4 or 5 hurricane.

At its peak, Hurricane Irma, a category 5 hurricane, was twice the strength of the Great Storm of 1987 – the most violent storm to ever hit the UK.

How does monitor hurricanes?

When we’re monitoring a tropical storm, we use a variety of sources to give us a detailed overview of the situation.

Depending on where a storm is predicted to make landfall, we will often monitor local news sources and government and disaster management agency websites, to understand how governments and local agencies are preparing for and responding to the storm.

We continue to monitor the situation after the storm has made landfall to understand the impact on affected communities, and to see if there will be an emergency shelter need.

We use our response criteria to make the decision around whether or not we are in a position to respond.

Find out more about how we prepare for Hurricanes.

Responding after a hurricane

Being deployed in the aftermath of either a hurricane or a typhoon presents many unique challenges.

Constant monitoring and communication between teams at HQ and on the ground are essential to making sure the team are all aware of what the risks are, what the situation is and what the weather conditions are like.

Watch this video to find out what our response teams can expect when they arrive in-country.

How do we support hurricane-stricken communities?

Dealing with the aftermath of a hurricane or typhoon can be very challenging. Whole communities can be destroyed, from people’s homes to vital infrastructures such as roads, communication lines, power and medical supplies.

Despite the challenges, we often respond to places that are hit by tropical storms. After hurricane Irma and Maria wreaked havoc in 2017, we have provided essential aid to over 2,000 families across five islands in the Caribbean. See how we’ve supported families.

By providing emergency shelter, people can have somewhere warm to stay and feel safe, which makes the process of recovery a whole lot easier.

‘We just kept praying, hoping, and waiting’.

The roof of Amy’s house in Barbuda was blown off and everything was damaged by water.

95% of all houses on Barbuda were destroyed by the Hurricane. This photo is just one example of the devastation caused.

Hurricane Maria damaged or flattened almost every building in Dominica, leaving the island with no power and little water for days.

A team returned in Dominica, July 2018, to speak with families who received aid after the devastation of 2017. aid arriving in Barbuda. We provided aid to over 2,000 families across five islands in the Caribbean.

Recovery in Dominica was slow, but steady. Here, two locals are in the process of fixing their roof with a tarpaulin, 2017.

Simon has lived in Wesley, Dominica for over 60 years. He had built his home himself and lived alone, as his four children are grown-up and have gone overseas. When the hurricane hit Wesley, he tried to shelter at a church, but the category 5 hurricane had damaged that, too.

We supported Simon with essential aid to rebuild his home and feel safe once again.

Sarita lives with her husband Avendale and their daughters in Woodford Hills, Dominica. When hurricanes Irma and Maria devastated the island, their home was severely damaged. Avendale works as a builder, so the family helped the community rebuild their homes using aid.
