SITUATION OVERVIEW
------------------
TROPICAL STORM 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 TROPICAL STORM EXTENDS
ACROSS THE BIG ISLAND AND MAUI COUNTY THIS MORNING AND WILL SPREAD
NORTHWEST TO REACH OAHU AND KAUAI LATER THIS MORNING. THE CENTER OF
TROPICAL STORM LALA REMAINS LOCATED WEST OF THE BIG ISLAND AND WILL
CONTINUE GENERALLY WESTWARD, TRACKING SOUTH OF THE ISLAND CHAIN TODAY.
DO NOT FOCUS ON THE EXACT FORECAST TRACK OR INTENSITY OF LALA AS
IMPACTS EXTEND WELL BEYOND THE CENTER OF THE TROPICAL STORM.
RAINFALL BETWEEN 15 TO 30 INCHES HAS BEEN OBSERVED OVER THE LAST
18 HOURS FOR THE EASTERN AND SOUTHERN BIG ISLAND. RAIN RATES HAVE
GENERALLY DECREASED TO ONE INCH PER HOUR OR LESS FOR THE BIG ISLAND.
THE THREAT FOR FLOODING CONTINUES FOR THE BIG ISLAND AND MAUI COUNTY
AND SPREADS TO THE REST OF THE STATE LATER THIS MORNING. 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 2 TO 4 INCHES ACROSS THE BIG ISLAND WITH
4 TO 6 ADDITIONAL INCHES OF RAIN FOR THE SMALLER ISLANDS. 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.
WINDS AND WIND GUSTS ON THE BIG ISLAND AND ACROSS MAUI HAVE DECREASED
EARLY THIS MORNING. SUSTAINED WINDS ARE NOW MOSTLY 25 MPH OR LESS FOR
THESE ISLANDS, THOUGH WIND GUSTS UP TO 60 MPH ARE STILL OCCURRING
ALONG THE SADDLE ROAD AND PORTIONS OF MAUI. SUSTAINED WINDS OF 20 TO
30 MPH CONTINUE FOR THE OTHER ISLANDS, WITH ISOLATED MOUNTAIN AND
DOWNSLOPE LOCATIONS, PARTICULARLY ON MOLOKAI, EXPERIENCING GUSTS AS
HIGH AS 80 MPH. TROPICAL STORM CONDITIONS, WITH SUSTAINED WINDS OVER
39 MPH, ARE STILL EXPECTED ACROSS THE STATE THROUGH THIS 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 SUBSIDING FOR THE BIG ISLAND BUT IS CURRENTLY PEAKING
FOR MAUI COUNTY. SURF WILL CONTINUE TO BUILD FURTHER WEST, PEAKING
OVER THE NEXT SEVERAL HOURS FOR OAHU AND LATER THIS MORNING FOR KAUAI.
SOME INCREASE IN SURF IS ALSO POSSIBLE TODAY ALONG EXPOSED
SOUTH-FACING SHORES AS LALA CONTINUES WESTWARD. SIGNIFICANT BEACH
EROSION AND OVERWASH ARE STILL POSSIBLE ACROSS VULNERABLE COASTAL
INFRASTRUCTURE.
POTENTIAL IMPACTS

* WIND:
POTENTIAL IMPACTS FROM THE MAIN WIND EVENT ARE NOW UNFOLDING ACROSS
THE BIG ISLAND OF HAWAII AND MAUI COUNTY. REMAIN WELL SHELTERED FROM
LIFE-THREATENING WIND HAVING ADDITIONAL EXTENSIVE IMPACTS. IF
REALIZED, THESE IMPACTS INCLUDE:
- CONSIDERABLE ROOF DAMAGE TO STURDY BUILDINGS, WITH SOME HAVING
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
ACCESS ROUTES IMPASSABLE.
- LARGE AREAS WITH POWER AND COMMUNICATIONS OUTAGES.
POTENTIAL IMPACTS FROM THE MAIN WIND EVENT ARE ALSO NOW UNFOLDING
ACROSS THE REST OF THE STATE. REMAIN WELL SHELTERED FROM DANGEROUS
WIND HAVING ADDITIONAL LIMITED TO SIGNIFICANT IMPACTS.
* FLOODING RAIN:
POTENTIAL IMPACTS FROM THE FLOODING RAIN ARE STILL UNFOLDING ACROSS
THE BIG ISLAND OF HAWAII AND MAUI COUNTY. REMAIN WELL GUARDED AGAINST
LIFE-THREATENING FLOOD WATERS HAVING ADDITIONAL DEVASTATING IMPACTS.
IF REALIZED, THESE IMPACTS INCLUDE:
- EXTREME RAINFALL FLOODING MAY PROMPT NUMEROUS EVACUATIONS AND
RESCUES.
- RIVERS AND TRIBUTARIES MAY OVERWHELMINGLY OVERFLOW THEIR BANKS
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
ROUTES. STREETS AND PARKING LOTS BECOME RIVERS OF RAGING WATER
WITH UNDERPASSES SUBMERGED. DRIVING CONDITIONS BECOME VERY
DANGEROUS. NUMEROUS ROAD AND BRIDGE CLOSURES WITH SOME WEAKENED
OR WASHED OUT.
POTENTIAL IMPACTS FROM THE FLOODING RAIN ARE STILL UNFOLDING ACROSS
THE REST OF THE STATE. REMAIN WELL GUARDED AGAINST LIFE-THREATENING
FLOOD WATERS HAVING ADDITIONAL LIMITED TO EXTENSIVE IMPACTS.
* SURGE:
POTENTIAL IMPACTS FROM THE MAIN SURGE EVENT ARE NOW UNFOLDING ACROSS
THE BIG ISLAND OF HAWAII AND MAUI. REMAIN WELL AWAY FROM LOCALLY
HAZARDOUS SURGE HAVING POSSIBLE LIMITED IMPACTS. IF REALIZED, THESE
IMPACTS INCLUDE:
- LOCALIZED INUNDATION WITH STORM SURGE FLOODING MAINLY ALONG
IMMEDIATE SHORELINES AND IN LOW-LYING SPOTS, OR IN AREAS
FARTHER INLAND NEAR WHERE HIGHER SURGE WATERS MOVE ASHORE.
- SECTIONS OF NEAR-SHORE ROADS AND PARKING LOTS BECOME OVERSPREAD
WITH SURGE WATER. DRIVING CONDITIONS DANGEROUS IN PLACES WHERE
SURGE WATER COVERS THE ROAD.
- MODERATE BEACH EROSION. HEAVY SURF ALSO BREACHING DUNES, MAINLY
IN USUALLY VULNERABLE LOCATIONS. STRONG RIP CURRENTS.
- MINOR TO LOCALLY MODERATE DAMAGE TO MARINAS, DOCKS, BOARDWALKS,
AND PIERS. A FEW SMALL CRAFT BROKEN AWAY FROM MOORINGS.
* TORNADOES:
POTENTIAL IMPACTS FROM TORNADOES ARE STILL UNFOLDING ACROSS THE
HAWAIIAN ISLANDS. REMAIN WELL BRACED AGAINST A TORNADO EVENT HAVING
POSSIBLE LIMITED IMPACTS. IF REALIZED, THESE IMPACTS INCLUDE:
- THE OCCURRENCE OF ISOLATED TORNADOES CAN HINDER THE EXECUTION
OF EMERGENCY PLANS DURING TROPICAL EVENTS.
- A FEW PLACES MAY EXPERIENCE TORNADO DAMAGE, ALONG WITH POWER
AND COMMUNICATIONS DISRUPTIONS.
- LOCATIONS COULD REALIZE ROOFS PEELED OFF BUILDINGS, CHIMNEYS
TOPPLED, MOBILE HOMES PUSHED OFF FOUNDATIONS OR OVERTURNED,
LARGE TREE TOPS AND BRANCHES SNAPPED OFF, SHALLOW-ROOTED TREES
KNOCKED OVER, MOVING VEHICLES BLOWN OFF ROADS, AND SMALL BOATS
PULLED FROM MOORINGS.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------

FLOODING IS NOT A CONCERN.
IF YOU ARE PRONE TO FLOODING, BE PREPARED FOR THE POSSIBILITY OF A
QUICK AND DRAMATIC RISE IN WATER LEVELS.
