Just a quick note as I hope everyone has taken precautions in Costa Rica and Nicaragua as Hurricane Otto has intensified to a Category 2 hurricane just before landfall later today. Let’s hope that there is little to no loss of life with this one. Latest NHC advisory is below.

***********************

Sorry for being late posting this but with family coming in and my preps for Turkey Day being focused on food, getting my antennas for the old shack in order, and an overwhelming workload, it has delayed me from posting as much lately. Heck, I might even get to post some Shortwave logs for once! That being said, Costa Rica is about to get slammed with a rare hurricane (last time was 1851!!!!) and this late in the season will make a huge mess of the dirt roads and mountains causing a massive risk for mudslides.

Good luck to my readers and friends down there!

Here is the latest:

DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 700 AM EST (1200 UTC), the eye of Hurricane Otto was located by a
reconnaissance plane near latitude 11.0 North, longitude 82.9 West.
Otto is moving toward the west near 8 mph (13 km/h), and this motion
is expected to continue today. A faster motion toward the west or
west-southwest is forecast to begin tonight and continue through
early Saturday. On this track, the center of Otto will make landfall
within the hurricane warning area today, and move across southern
Nicaragua and northern Costa Rica through this evening. The center
of Otto is expected to reach the Pacific coast of southern Nicaragua
or northern Costa Rica tonight.

Data from a reconnaissance plane indicate that the maximum
sustained winds have increased to near near 105 mph (165 km/h) with
higher gusts. Some additional strengthening is possible before
landfall. Weakening is expected after landfall, and Otto is forecast
to weaken to a tropical storm by tonight.

Hurricane-force winds extend outward up to 10 miles (20 km) from
the center and tropical-storm-force winds extend outward up to 70
miles (110 km).

The minimum central pressure just reported by an Air Force Reserve
reconnaissance plane was 976 mb (28.82 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL:  Total rainfall of 6 to 12 inches, with isolated amounts
of 15 to 20 inches, can be expected across northern Costa Rica and
southern Nicaragua through today. These rains will likely result in
life-threatening flash floods and mudslides.

Outer rain bands from Otto are expected to produce rainfall
accumulations of 4 to 8 inches over San Andres and Providencia
islands, and the higher terrain of central and western Panama and
southern Costa Rica through this morning.

WIND:  Hurricane conditions are expected to reach the hurricane
warning area late this morning or early this afternoon, with
tropical storm conditions expected to begin shortly. Hurricane
conditions are possible in the hurricane watch area today.

Tropical storm conditions are expected within the warning area
on the Caribbean coast of Nicaragua today. Tropical storm conditions
are expected in the warning area along the Pacific coasts of Costa
Rica and Nicaragua by this evening.

STORM SURGE:  The combination of a dangerous storm surge and large
and destructive waves could raise water levels by as much 4 to 6
feet above normal tide levels in areas of onshore flow within the
hurricane warning area.

SURF:  Swells generated by Otto are likely to cause life-threatening
surf and rip current conditions over the next several days along the
coasts of Panama, Costa Rica, and Nicaragua.  Please consult
products from your local weather office.
