Buresh Blog: Another 90 degree day then a brief taste of fall.... arctic sea ice way below average

Oct. 23, 2019 — 5 weeks left in the hurricane season - "Talking the Tropics With Mike" updated every day.

Summer is trying to hang on.  Yet another 90-degree day (91) Tue., 10/22 was the 100th 90 degree day of the year.  The avg. for a year is 82 days, & we were just 5 days from the latest 90 degree day ever recorded - Oct. 27th.

The unseasonable heat occurred ahead of a strong cold front that dipped temps. the next (Wed., 10/23) morning to the coolest in nearly 6 months! But the cool air will not be around long & heat & especially humidity return for the weekend into a good part of the following week (I always say you have to wait 'til Halloween - at least - for when cool air will move in & stay).

While we've had some chilly air enter the Northern & NW U.S. this month, arctic ice is well below avg. - some 3 million sq km below the avg. of 8.4 million sq km. - from the National Snow & Ice Data Center.  This despite a very snowy spring & early summer that saw snow on the ground into late July in Greenland.

Interesting read from phys.org - on Florida mangroves - click here.  Mangroves are tropical, salt-tolerant trees that die of during severe freezes.  Florida's last widespread significant freeze was in Jan., 2010 but a long term widespread severe freeze has not occurred since the 1980s.  On average, these harsh freezes occur every 10-30 years, so we're due to say the least.  The article points out that data doesn't necessarily point ot climate change for the latest move north by the mangroves which serve a vital role in our coastal environment: (1) protect against storm surge during hurricanes.... (2) good at removing carbon (greenhouse gas) from the atmosphere.

Lots of talk & controversy regarding a major EF-3 tornado in Dallas Sunday night (Oct. 20th) & the manner in which tornado warnings were - or were not - communicated via television.   The FCC may very well become involved.  The NBC affliate was showing the Dallas Cowboy game which led the station only occasionally breaking into programming - including weather/storm crawls - despite a large EF-3 damage moving through populated areas of North Dallas.  See an interesting video timeline * here * showing all four local t.v. stations at the same time & their handling of the tornado warning.  Video & pics from "LiveScience" - here.

This protocol is constantly scrutinized by consumers.  Action News Jax policy is to break into regular programming for all tornado warnings.

Jamie Rhome, National Hurricane Center, has been awarded the Service to America medal for his pioneering work on storm inundation & storm surge including public warnings.  I've had a chance to interview Jamie on multiple occasions.... I've followed his work & research... & now I use many of the forecast products he's helped develop to warn & advise you about storm surge & water levels during a tropical storm or hurricane.  Job well done!

Example of a storm inundation map - forecast feet above ground level.  This map has proven to be very helpful - especially along the coast during hurricanes.  These proved quite accurate along our coast during Matthew & Irma.
