I just went to https://24timezones.com/timezone-map to complain that they don't have the weather on their site. The fiends!

@Tomber42
Another site has this. It is potentially in digital form (after someone has drawn it) and can thus be obtained. Perhaps some data trading is in order?

See image. Change "lightnings" to "lightning".

Reported 13 days ago in general comments area as well.

Dorian is currently (as of this writing) reported as 916 mbar ("Minimum central pressure") by NOAA.
But on Windy, the centre is shown as 956 mbar. (Or a near to centre isobar?).

Is there a reason for the mismatch? Can this be improved? Windy intense lows are consistently reporting higher than 'official' source actual minimal lows.

References below: A) NOAA Dorian status for 1100UTC and B) Current Windy image for approx same time.

A) Excerpt from NOAA Dorian status
SUMMARY OF 700 AM EDT...1100 UTC...INFORMATION

LOCATION...26.7N 78.2W
ABOUT 35 MI...50 KM ENE OF FREEPORT GRAND BAHAMA ISLAND
ABOUT 120 MI...190 KM E OF WEST PALM BEACH FLORIDA
MAXIMUM SUSTAINED WINDS...165 MPH...270 KM/H
PRESENT MOVEMENT...W OR 280 DEGREES AT 1 MPH...2 KM/H
MINIMUM CENTRAL PRESSURE...916 MB...27.05 INCHES

B) Image sample from Windy

Or even readings at measurement stations?

A favourite video:

Wish there were a 2018 edition.

I get this when I turn on the weather radar display sometimes, or at the end of a real time "play".

Should look more like:

Frankly, I'd prefer the raw Environment Canada data overlaid, such as:

And, please turn off lightning and sound as defaults!

Windy runs far smoother in Safari than in Chrome. (Mac OS).

Title says it all. Amount sort of works (after currency conversion). But I want to be sure.
Thx.

In science, time is generally represented as left to right so the the display as is, is correct in that sense. This carries to things like video progression as well. My 2 cents.

Thx!4321

Re: weather radar layer: "Show lightning" is the correct spelling - please delete the 's'.

I'd also prefer the default settings for lightning and sound to be off.

Is the accumulation amount for the 3 hours ending at that time. ie: at 10:00, 9 cm is forecast to fall between 7:00 and 10:00?

Thanks.

PS: Finally occurred to me why the hours seem wonky until I factor in our time zone... (-5 UTC) as the 3 hour chunks are UTC 0:00 based.

Edit : clarified.

This may be too simplistic. I don't know.

Where do I find the timestamp for when the ECMWF forecast data was updated and/or incorporated into Windy?

Can't find account period end info.
Can't find renewal price.
Can't find if it is automatic.

Thanks.

Thanks! Funny thing is I have stumbled upon that before (but I picked myself up and wandered off as if nothing had happened...)

Strange that Sudbury isn't on there.

In the meantime, just use Environment Canada's site. The new presentation has a lot of sucky elements (ie: not north aligned except in the middle longitude of Canada. Make's St-John's esp whacky looking...). But does have transparency settings for the radar image. Also shows US radar down as far as Puerto Rico, but the map is missing south of Ohio latitudes.

(The iPhone app Env. Canada is correctly north up).

As to Windy, I've requested they add an option to present the weather radar 'raw' (as Environment Canada do), but that's been ignored. The current algorithm often drops the last image or has strange artifacts.

Edit: clarification.

I would like to be able to "tag" a leading edge of a radar (rain/snow) and have:

Speed
Direction of travel (degrees true)

I would like the radar image to be "propagated" for up to 3 or 4 hours forward.
(1st order should be easy; 2nd order feasible).
