HURRICANE UPDATE: GONZALO TRACKS AWAY FROM ABACO, BAHAMAS

STOP PRESS – UPDATE Following yesterday’s post (below), the hurricane’s tendency to track further away from the Bahamas is confirmed by later models, for examples this one from Wunderground. So I think we are officially ‘off-risk’. But Bermuda is definitely not… Anyway, read on a bit and you will find out how hurricanes get their names!

Yesterday I posted on my FB page an NOAA hurricane tracking map update for Hurricane Gonzalo, currently rated Cat. 2 on the SAFFIR-SIMPSON SCALE. It is making its way north through the Caribbean right now, and at one stage the storm cone looked on a possible course for the Bahamas. Abaco has been spared a major cyclone for a couple of years. However memories are very recent of Hurricane Irene (2011) which passed directly over Abaco as a Cat. 3 storm; and Hurricane Sandy (2012) that passed marginally to the east with (at that stage) an intensity of a Cat. 1 before going on to wreak havoc further north. During those ‘extreme weather events’ I posted regularly about them, with tracking maps and photos. At the time of Irene there was remarkable little information around online and I got a huge number of hits – 5000+ in a day, 15,000+ in a week. I also replied to lots of inquiries from the Bahamas, US and Canada, both general (“How are things at Cherokee?”) to very specific (“Do you happen to know if my boat ‘Blowdakidzinheritanz’ moored in Little Harbour is Okay?”).

I  have been surprised at the response the map generated by way of ‘Likes’ and comments expressing relief… So from my current safe distance of precisely 4250.00 miles from Marsh Harbour, I am posting an update with helpful maps and a bit of general hurricane info. The agencies all agree that Gonzalo will hook east as it progresses northwards. The Bahamas outlook is promising, though for example Bermuda looks to be at risk.  There’s more on hurricanes on the page ABACO WEATHER. I always think that Wunderground produce the clearest maps for general purposes, though there’s a great deal more information to be had from the NOAA site, to which there’s a direct link in the Sidebar (I’ve moved it to near the top for the time being).

THE SAFFIR-SIMPSON SCALE

Here is a reminder of how tropical storms and hurricanes are measured for intensity, as decreed by the S-SS, followed by the National Hurricane Center’s explanation of the gradations of relative intensities.

Saffir-Simpson Scale (Wiki) jpgT

The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based on a hurricane’s sustained wind speed. This scale estimates potential property damage. Hurricanes reaching Category 3 and higher are considered major hurricanes because of their potential for significant loss of life and damage. Category 1 and 2 storms are still dangerous, however, and require preventative measures. In the western North Pacific, the term “super typhoon” is used for tropical cyclones with sustained winds exceeding 150 mph.

Category   Sustained Winds Types of Damage Due to Hurricane Winds
1 74-95 mph
64-82 kt
119-153 km/h
Very dangerous winds will produce some damage: Well-constructed frame homes could have damage to roof, shingles, vinyl siding and gutters. Large branches of trees will snap and shallowly rooted trees may be toppled. Extensive damage to power lines and poles likely will result in power outages that could last a few to several days.
2 96-110 mph
83-95 kt
154-177 km/h
Extremely dangerous winds will cause extensive damage:Well-constructed frame homes could sustain major roof and siding damage. Many shallowly rooted trees will be snapped or uprooted and block numerous roads. Near-total power loss is expected with outages that could last from several days to weeks.
3
(major)
111-129 mph
96-112 kt
178-208 km/h
Devastating damage will occur: Well-built framed homes may incur major damage or removal of roof decking and gable ends. Many trees will be snapped or uprooted, blocking numerous roads. Electricity and water will be unavailable for several days to weeks after the storm passes.
4
(major)
130-156 mph
113-136 kt
209-251 km/h
Catastrophic damage will occur: Well-built framed homes can sustain severe damage with loss of most of the roof structure and/or some exterior walls. Most trees will be snapped or uprooted and power poles downed. Fallen trees and power poles will isolate residential areas. Power outages will last weeks to possibly months. Most of the area will be uninhabitable for weeks or months.
5
(major)
157 mph or higher
137 kt or higher
252 km/h or higher
Catastrophic damage will occur: A high percentage of framed homes will be destroyed, with total roof failure and wall collapse. Fallen trees and power poles will isolate residential areas. Power outages will last for weeks to possibly months. Most of the area will be uninhabitable for weeks or months.

TROPICAL STORM CHANTAL HEADS FOR BAHAMAS & ABACO: REGULAR UPDATES

ORIGINAL POST

The 9th July, the season of storms starts to loom, and Chantal is first off the meteorological starting blocks. The reason I am posting this now is because the present 5-day predictions (see NOAA charts below) has Chantal heading directly for the Bahamas in general, and Abaco in particular. So this may be one to keep a weather eye on over the next few days…

HURRICANE SANDY: CUBA, BAHAMAS (TRACKING / PATH MAPS, LATEST ABACO UPDATES 25 OCTOBER)

UPDATE 25 OCT 05.00 EDT HURRICANE SANDY CLEARING CUBA AS CAT. 2

Three hours passing has made a further difference, and not for the better. The landmass of Cuba, far from slowing the storm, has seen it intensify to Cat 2 – though so far that is predicted only as far as the south Bahamas… (Map 1). However the eastward drift into the Atlantic is still detectable – see Abaco detail, Map 2

UPDATE 25 OCT 02.00 EDT HURRICANE SANDY MAKES CUBA LANDFALL

As Sandy reaches the south coast of Cuba, two things have become clear overnight. First, the storm’s strength is now predicted at Cat 1 until it clears into the Atlantic north of the Bahamas – there will be no reduction to TS status in the south Bahamas (Map 1) Secondly, the news for Abaco is that a slight drift of the spine of the storm to the east can be detected (see Abaco Detail, Map 2). Yesterday, the eye was due to pass pretty much directly over MH and indeed (like Irene last year) the Delphi Club and Rolling Harbour. The shift may of course have no significant effect on the storm’s power, but if the eye’s path could continue to drift further east… Map 3 is the ‘hot’ map from 04.00 EDT today

FLIGHT ADVISORY As many on Abaco may already have found, there are flight disruptions from Nassau – I know of one person who couldn’t get to MH last night. So visitors following this blog and planning an imminent flight need to keep a careful eye on the situation, which given the path of the storm is likely to worsen.

I will not be in a position to post much in the way of updates between now and Monday – by which time Sandy should have cleared to the north of the Bahamas. The interactive tracker link at the top of this page is an excellent resource, especially as you can input a precise location. There is luckily a wealth of information out there on the internet – far more than for Irene last year. I notice too that Abaco residents are busy exchanging information on Facebook. While we are away, we’ll be thinking of all those in the path of the storm…

UPDATE 24 OCT 18.00 EDT HURRICANE SANDY CROSSING JAMAICA

Sandy is now a Cat 1 hurricane as it crosses Jamaica and heads for eastern Cuba. As the latest projections show, the prospects for the Bahamas have worsened: hurricane force is expected over central and northern islands (see map below for Abaco detail)
