Email Weather Alerts & Warnings

Want to be warned when the wind goes over 50 mph or if there's likely to be ice on the roads on the way to work?

Following a request on this Blog, Hebrides Weather is now offering a Weather Warning & Alert Email Service.
The way it works is this:
There are thresholds set by Hebrides Weather and if any of these (listed below) are exceeded then an email is automatically sent to all those who have requested it.
It should be stressed that these warnings & alerts are for actual weather events that have already happened, they are not an advanced warning service!!

The thresholds are as follows:

• Maximum wind gust above 64 knots (Hurricane Force)
• Mean wind speeds over 44 knots (50 mph)
• More than 25mm (1 inch) of rain in the last hour
• More than 50mm (2 inches) or rain in the last 6 hours
• Temperature falls below 0°C
• Temperature rises above 30°C
• Windchill falls below -15°C
• Barometric pressure rises above 1080 hPa
• Barometric pressure falls below 800 hPa
• Barometric pressure fall more than 10 hPa in 1 hour

There is one further type of alert, the Frost Protection Alert which is issued if the following conditions occur:

• Time of day is between 9pm & 9am (over night)
• Dew point is less than 3°C
• Air temperature is 6°C or less
• Temperature has dropped more than 1°C in the last hour
• Wind speed has been 2 knots or less in the last hour

If you would like to receive these emails then please send your email address using the Contact form and choose "Weather Warnings" in the department to contact menu.

You are free to request that your email address be removed from the list at any time and your email address will not be passed to any third party.

Frost & Ice Warnings

I have introduced a new facility to the website, frost and ice warnings & alerts.
When the outside air temperature goes below 3°C "FROST WARNING" will appear below the banner on all the web site pages. The same text will also appear at the top of the dashboard on the home page.
If the temperature falls below 0°C the "ICE ALERT" will also appear.
Once the temperature increase above 4°C then the warnings will start to disappear and all warnings will be removed once the it's above 7°C.

As usual, I welcome any comments.

Here's an example:

Tropical Storm Grace

Tropical Storm Grace has appeared on the map and is currently 400 miles West of Portugal heading Northeast at around 25mph.
The average wind speeds are 65mph, but these are expected to reduce to around 50mph by Tuesday.
The forecast tracks have the storm heading towards Southern Ireland where it may turn East and cross Wales and Central England on Wednesday night or Thursday or it could run along the Channel Coast.
The wind speeds are difficult to predict at this stage but I don't think it will be that strong by the time it reaches the UK coast.

To see the latest updates on where Grace is located then check our Tropical Storm & Hurricane Page.

Tropical Storm Grace has now merged with a frontal system off the Southwest of Ireland and, although it may produce gale force winds, the remains of this storm are not likely to cause any serious threat to the UK or Ireland.
The following is the last statement from the National Hurricane Centre in the U.S:

...Grace absorbed by a frontal system...
at 1100 PM AST...0300 UTC...the remnants of Tropical Storm Grace
were located near latitude 49.7 north...longitude 13.4 west or
about 210 miles...335 km...southwest of cork Ireland.
The remnants of Grace are moving toward the north-northeast near 26
mph...43 km/hr...and this motion is expected to continue until
dissipation.
Maximum sustained winds have decreased to near 50 mph...85
km/hr...with higher gusts.  The remnants will likely continue to
produce a small area of gale force winds through early Tuesday.
Tropical storm force winds extend outward up to 85 miles...140
km...mainly southeast of the center.
Estimated minimum central pressure is 986 mb...29.12 inches.
...Summary of 1100 PM AST information...
location...49.7n 13.4w
maximum sustained winds...50 mph
present movement...north-northeast or 25 degrees at 26 mph
minimum central pressure...986 mb
this is the last public advisory issued by the National Hurricane
Center on this system.  Additional information on the remnants of
Grace can be found in high seas forecasts issued by the United
Kingdom meteorological office under WMO header wont54 EGRR.
