One of the quickest things I've ever seen go from initial invest to tropical storm.

Looks like Colin's making up for how long Bonnie took

Bam! Just like that
Wow, so we go from just 1 named storm in all of June to now 2 NS in July... and it is only July 2 lol.
Dang, Nature sure loves to pull some funny tricks

I felt quite confident about my 2 NS in July guess, but then Bonnie formed on July 1 instead of June 30 and Colin just randomly forms on July 2. And now we're already at 2 storms with pretty much the entire month to go. I don't think I'll win the poll this month.

From NHC discussion:

A small area of low pressure formed along a surface trough just
offshore of Savannah, Georgia, yesterday morning and moved inland
across the Lowcountry of South Carolina by the evening. Deep
convection formed near the low center as it was moving inland and
has persisted and become better organized over the past 6 to 12
hours. In addition, surface observations and ASCAT data from
02-03 UTC indicated that an area of sustained 35-kt winds had
developed offshore and near the coast of South Carolina. As a
result, and rather unexpectedly, Tropical Storm Colin has formed
near the South Carolina coast, centered just inland a bit to the
northeast of Charleston.

Don't think anyone saw this coming...

[ElectricStorm]

Well that was unexpected... Somehow became a TS over land too, crazy.

[Kingarabian]

Technically this formed earlier as it had a strong LLC for a while. I'm assuming it'll be adjusted in the off season.

Absolutely. I think this will be BT'd as having formed offshore about 18 hours before advisories were initiated.

Similar thing happened with Julia in 2016 and they moved up the formation point about 12-18 hours in post-season.

[MarioProtVI]

Aaand I was right. Incredible speed at which it developed, and it does remind me of Julia 2016 when it basically did the same thing.

One named storm in June is a lot, not a “just”

I love it when models don’t see even a hint of it coming.

[Jr0d]

Based on weather observations of tropical storm conditions, the NHC had to name it.

With how far we've forecasting and computer models, it always is interesting when one if these storms pops up literally overnight.

Unfortunately coastal areas were experiencing tropical storm conditions before any warnings had a chance to be issued. At least it is just a minimum storm.

Storms with small cores like Colin's can intensify extremely quickly, lucky wind shear, land and other inhibitors have capped the intensity.

[Teban54]

At least this one is not as sloppy as Colin 2016

[TallyTracker]

Wow! I haven’t been this surprised by a TS formation in a while! Models really missed this one!

[wwizard]

So is this a landfalling storm?

[wxman57]

Not much to "landfall". It's inland west of Myrtle Beach. Coastal winds are 5-15 kts. It peaked yesterday afternoon and has been weakening.

[jimpsummers]

Popped up quickly just offshore in the same place. I watched this one yesterday (as with Danny last year) and thought that this little thing is wrapping up quickly. Got some beneficial rain yesterday because of the onshore flow here, so I appreciate that!

[wxman57]

By the way, 2 weeks ago I said to watch for a TS developing offshore of the Carolinas on July 4th weekend.

[Hypercane_Kyle]

Definitely TS Julia vibes (ironically, another 2016 storm like Otto was) today with Colin's formation.
