SATELLITE ANALYSIS AND TRENDS...UPDATING THE PREVIOUS SPENES MESSAGES
WITH NEW INFO FROM THE MOST RECENT AUTOMATED SATELLITE ESTIMATING
TECHNIQUES. THE MOST RECENT HYDROESTIMATOR IS INDICATING A 6 HOUR MAX
OF AROUND 7" WITH THE AREA OF MORE PERSISTENT COLDER TOPS OFFSHORE
JUST SE OF THE BIG ISLAND WHILE THE QMORPH TECHNIQUE IS SHOWING OVER 5"
THERE. INFORMATION FROM THE 18Z ENSEMBLE-TRAP FOR DARBY SHOWS ROUGHLY
4.5" AMOUNTS IN A 6 HOUR PERIOD. IT IS TO BE EMPHASIZED THAT THESE
TECHNIQUES DO NOT TAKE INTO ACCOUNT TERRAIN EFFECTS AND THE QMORPH AND
E-TRAP TECHNIQUES GENERALLY DO NOT DO WELL WITH SYSTEMS WHICH EXHIBIT
FLUCTUATIONS IN CONVECTIVE INTENSITY AND/OR SHEARING.
.
CURRENT TRENDS FROM IR IMAGERY ARE SHOWING A SIGNIFICANT FLARE UP OF
COLDER TOPPED CONVECTION ALONG WITH LIGHTNING STRIKES (LIGHTNING DENSITY
PRODUCT) OVER THE SE PORTION OF THE BIG ISLAND AS THE CIRCULATION OF DARBY
MOVES ONSHORE IN THE KAU DISTRICT PER INFO FROM THE RECENT ADVISORY FROM
THE CPHC.
.
SHORT TERM OUTLOOK VALID 0115-0715Z...MEDIUM TO HIGH CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...WITH RECENT TRENDS INDICATING A SIGNIFICANT
INCREASE IN CONVECTION INLAND OVER THE SE PART OF THE BIG ISLAND LIKELY
ENHANCED FURTHER AS THE E WIND FLOW ENCOUNTERS THE FAVORED TERRAIN
AND WITH OFFSHORE TRENDS SHOWING THE COLDER TOPPED ACTIVITY SHIFTING
STEADILY TO THE W AND NW AND CLOSER TO THE COAST, BELIEVE THIS IS THE
BEGINNING OF A PERIOD OF VERY INTENSE RAINFALL ESPECIALLY FOR THE E,
SE, AND S PORTIONS OF THE BIG ISLAND.
