Name assigned from 2016 list of preselected names, when promoted to a tropical storm by (U.S.) National Hurricane Center, on Michaelmas.  Now promoted not only to a hurricane today (08:00?), but also to a major hurricane (11:00?): "MAXIMUM SUSTAINED WINDS... 120 MPH... 195 KM/H" (14:00).

Current forecast early landfalls (landsfall?), albeit mine very unofficial as verbalized from the NHC "5-Day Forecast Cone for Storm Center" map(s)

• :

Mon. 08:00: Jamaica.
Mon. 20:00: Cuba, approx. 76°W, near Santiago de Cuba (Cuba Oriente, thus W. of Git'mo, the latter being near 75°W).
Tue. 20:00: Tropic of Cancer & approx. 76°W (thus approx. Great Exuma I., Bahamas); or if[/b]  it were to veer farther W'ward (altho' not officially forecast) Wed. 08:00: Florida Upper Keys.  It needs to begin its sharp starboard turn Sat. (tomorrow) 08:00, if it's to begin making good on its current forecast to miss the U.S. Southeast

It was already unusually large when it was merely the tropical storm Matthew: So maybe a once-in-a-lifetime opportunity for CathInfo's owner-moderator to see his name go down into modern secular weather history.

Note *: NHC doesn't use generic maps.  Right now, <http://www.nhc.noaa.gov/refresh/graphics_at4+shtml/145010.shtml?5-daynl> seems to be refreshable manually to incorporate the trihourly NHC updates (i.e.: "145010" may uniquely designate the storm).  But sometimes it seems that each  forecast map is assigned a different Web address.  If so, start with <http://www.nhc.noaa.gov/>; scroll down to "Hurricane MATTHEW", then click "Warnings/Cone Static Images".  Times shown are U.S. Eastern Time currently in effect, thus Eastern Daylight Time.

Note @: E.g.: Palm Beach (E'most place in Florida) very close to 80°W; to Key Largo stretching approx. 80 1/4°W--80 2/3°W in the Upper Keys; to Key West outside 80 3/4°W in the Lower Keys.

And then there is this:

Strange trajectory, they have it making like a 90 degree turn North.

Indeed.  But the image that originally appeared in your reply (4:43 pm) might not continue to illustrate that: Are you aware that, because you chose to use a direct inclusion of the NHC image, it's automatically replaced by the current image from NHC?  Not only whenever anyone loads the CathInfo page that contains your reply, but also in at least some cases, when someone uses the 'back' button on a page loaded many hours earlier?   Alas, the NHC Web site is configured to be set up to redirect older images, so that the requesting browser loads the current image instead.

Note [...]: I seem to be unable to access older NHS NHC public advisories for confirmation of any I'd missed; the NHC Web site seems to be set up to redirect older advisories to the current one.

Aha!   Those issues have solutions:  I found the NHC archive page.  But mañana, already!

Aha! [....]  I found the NHC archive page.  But mañana, already!

I don't recall ever seeing a tropical storm intensify into a top-ranked hurricane like Matthew has thus far 

• :

Thu. 11:00:  70 mi./hr. sustained: Still a mere tropical storm.
Thu. 14:00:  75 mi./hr. sustained: Promoted to hurricane (pop the corks for CathInfo's owner-admin namesake over there in south-central Texas, and say a prayer on this Feast of St. Michael the Archangel)!
Thu. 17:00:  75 mi./hr. sustained.
Thu. 20:00:  75 mi./hr. sustained.
Thu. 23:00:  80 mi./hr. sustained.
Fri. 02:00: 100 mi./hr. sustained.
Fri. 05:00: 100 mi./hr. sustained.
Fri. 08:00: 105 mi./hr. sustained.

[....] key numbers from the (U.S.) National Hurricane Center:
[Fri] 11:00: 115 mi./hr. sustained.
[Fri] 14:00: 120 mi./hr. sustained.
[Fri] 17:00: 140 ?  mi./hr. sustained [×] [confirmed via archive].
[Fri] 20:00: 150 mi./hr. sustained.
[Fri] 23:00: 160 mi./hr. sustained.

Sat. 02:00: 160 mi./hr. sustained.
Sat. 05:00: 155 mi./hr. sustained: Demoted to cat.-4.
Sat. 08:00: 155 mi./hr. sustained.
Sat. 11:00: 145 mi./hr. sustained; slowed to 6 mi./hr. (9 KM/H).

At least it's been headed due W. since at least 05:00, no longer any compass bearing that's S. of W.   So it might turn out to be the beginning of the previously forecast turn (i.e.: rotation of its heading) to starboard, altho' we in Florida need it to be a more prompt turn than I believe we're eventually gonna see.  With the day's renewed solar energy, when & if it frees its S'ern outer bands from the drag of the S.-American coast (esp. Pta. Gallinas and the rest of La Guajira: the peninsular far-northern tip of Colombia), I assume it'll be able to crank up its sustained winds again.

Note #: The notorious Andrew (another liturgical-red II-rank major saint!) might be worthy competition, but I was living on the Left Coast at the time.  Altho' the WorldWideWeb had been released via UseNet newsgroups in August 1991, I suspect that the (U.S.) National Hurricane Center didn't yet have a WWW site to keep out-of-state spectators informed, back when Andrew arrived 1 year later (to the month).

Strange trajectory, they have it making like a 90 degree turn North. Those Southern Hurricanes usually head toward Yucatan and South of it.

Well, it did do that 90 degree turn North:

Matthew may hit the US as a Category 5 Hurricane

The colors are just the hurricane and the intensity of the storm. Like, this is a once in a decade storm and those are the colors the Weather Channel uses to express something like that.
