SITUATION OVERVIEW
------------------
HURRICANE LALA CONTINUES TO BRING DAMAGING WINDS, HEAVY RAINFALL
LEADING TO FLASH FLOODING, AND DANGEROUSLY HIGH SURF TO PORTIONS OF
THE STATE. HEAVY RAIN ASSOCIATED WITH THE HURRICANE EXTENDS ACROSS THE
BIG ISLAND AND MAUI COUNTY TONIGHT AND WILL SPREAD NORTHWEST TO REACH
OAHU EARLY SUNDAY MORNING AND KAUAI LATER SUNDAY MORNING. HURRICANE
LALA IS NOW CENTERED WEST OF THE BIG ISLAND AND WILL CONTINUE
GENERALLY WEST-NORTHWESTWARD, TRACKING SOUTH OF THE ISLAND CHAIN
THROUGH SUNDAY. DO NOT FOCUS ON THE EXACT FORECAST TRACK OR INTENSITY
OF LALA AS IMPACTS EXTEND WELL BEYOND THE CENTER OF THE HURRICANE.
RAINFALL BETWEEN 15 TO 25 INCHES HAS BEEN OBSERVED OVER THE LAST
18 HOURS FOR THE EASTERN AND SOUTHERN BIG ISLAND. PORTIONS OF KAU
DISTRICT HAVE RECENTLY OBSERVED RAINFALL RATES OF 3 TO 5 INCHES PER
HOUR, PRODUCING CATASTROPHIC FLASH FLOODING. FLOODING RAIN WILL
CONTINUE FOR PORTIONS OF THE BIG ISLAND OF HAWAII AS LALA PASSES. THE
THREAT FOR FLOODING INCREASES OVER MAUI COUNTY TONIGHT THROUGH SUNDAY
MORNING AND SPREADS TO THE REST OF THE STATE THROUGH SUNDAY. HEAVY
RAINFALL COULD PERSIST INTO MONDAY FOR SOME AREAS, MAINLY OVER THE
WESTERN END OF THE ISLAND CHAIN. LALA IS EXPECTED TO PRODUCE
ADDITIONAL RAINFALL TOTALS OF 4 TO 8 INCHES ACROSS THE BIG ISLAND AND
MAUI COUNTY AND 4 TO 6 INCHES ACROSS THE REMAINDER OF THE ISLAND
CHAIN. LOCALLY HIGHER AMOUNTS ARE POSSIBLE. WHILE THE HIGHEST RAINFALL
AMOUNTS WILL BE FOCUSED OVER WINDWARD AREAS AND HIGHER TERRAIN,
LEEWARD AREAS WILL ALSO HAVE A SIGNIFICANT FLOOD RISK.
SUSTAINED WINDS OF 35 TO 45 MPH WITH GUSTS AS HIGH AS 80 MPH ARE BEING
OBSERVED FOR LEEWARD KOHALA AND PORTIONS OF WEST MAUI TONIGHT.
25 TO 35 MPH SUSTAINED WINDS WITH GUSTS OF 40 TO 60 MPH ARE ALSO
ONGOING ALONG THE SADDLE ROAD AND LARGE PORTIONS OF MAUI. HURRICANE
CONDITIONS, WITH SUSTAINED WINDS OVER 74 MPH, REMAIN POSSIBLE ACROSS
THE BIG ISLAND THROUGH SUNDAY MORNING. TROPICAL STORM CONDITIONS, WITH
SUSTAINED WINDS OVER 39 MPH, ARE EXPECTED FOR PORTIONS OF MAUI COUNTY
THROUGH SUNDAY AFTERNOON AND THE WESTERN ISLANDS THROUGH SUNDAY
EVENING. IT IS VERY IMPORTANT TO NOTE THAT THE MOUNTAINOUS TERRAIN OF
THE ISLANDS WILL LIKELY PRODUCE LOCALIZED AREAS OF HIGHLY ENHANCED AND
DAMAGING WINDS, EVEN WELL AWAY FROM THE TROPICAL CYCLONE CENTER.
EAST SWELL IS BEGINNING TO SUBSIDE FOR THE BIG ISLAND BUT IS CURRENTLY
PEAKING FOR MAUI COUNTY. SURF WILL CONTINUE TO BUILD FURTHER WEST,
PEAKING EARLY SUNDAY MORNING FOR OAHU AND LATER SUNDAY MORNING FOR
KAUAI. SOME INCREASE IN SURF IS ALSO POSSIBLE ALONG EXPOSED
SOUTH-FACING SHORES AS LALA CONTINUES WESTWARD. SIGNIFICANT BEACH
EROSION AND OVERWASH ARE STILL POSSIBLE ACROSS VULNERABLE COASTAL
INFRASTRUCTURE.

WINDOW, DOOR, AND GARAGE DOOR FAILURES LEADING TO STRUCTURAL
DAMAGE. MOBILE HOMES SEVERELY DAMAGED, WITH SOME DESTROYED.
DAMAGE ACCENTUATED BY AIRBORNE PROJECTILES. LOCATIONS MAY BE
UNINHABITABLE FOR WEEKS.
- MANY LARGE TREES SNAPPED OR UPROOTED ALONG WITH FENCES AND
ROADWAY SIGNS BLOWN OVER.
- SOME ROADS IMPASSABLE FROM LARGE DEBRIS, AND MORE WITHIN URBAN
OR HEAVILY WOODED PLACES. SEVERAL BRIDGES, CAUSEWAYS, AND

IN MANY PLACES WITH DEEP MOVING WATER. SMALL STREAMS, CREEKS,
CANALS, ARROYOS, AND DITCHES MAY BECOME RAGING RIVERS. IN
MOUNTAIN AREAS, DEADLY RUNOFF MAY RAGE DOWN VALLEYS WHILE
INCREASING SUSCEPTIBILITY TO ROCKSLIDES AND MUDSLIDES. FLOOD
CONTROL SYSTEMS AND BARRIERS MAY BECOME STRESSED.
- FLOOD WATERS CAN ENTER NUMEROUS STRUCTURES WITHIN MULTIPLE
COMMUNITIES, SOME STRUCTURES BECOMING UNINHABITABLE OR WASHED
AWAY. NUMEROUS PLACES WHERE FLOOD WATERS MAY COVER ESCAPE

OF EMERGENCY PLANS DURING TROPICAL EVENTS.
- A FEW PLACES MAY EXPERIENCE TORNADO DAMAGE, ALONG WITH POWER
AND COMMUNICATIONS DISRUPTIONS.
